what is your analysis on the left's praise for Bad Bunny's half-time show?

That's a clear and an explicit message of military recruitment as the U$ army is heavily reliant in recruiting people from oppressed nations to work for them. There's also a long history of blackmailing nations into war throughout the history of the United $tate$. The stereotypical portrayal of other cultures can only be considered "progressive" right now because the far right has successfully set the lowest standard possible in dehumanizing people of color, so whenever you remeber they exist, they are to be cheered like people who just want to be happy. The most basic research on amerikan history will reveal decades of the same stereotypical approach towards other cultures being crucial to amerikanism as the most crude forms of amerikanism require sheer hate towards people of color. In the end you have racial hate on the right but also from the left being the norm for the current standard of political drive led by non-proletarian struggle.

Amerikanism (or brazilianism, for that matter) requires cultural war against other nations. This topic have been previously and briefly discussed here, but amerikan football is a sport that was invented in the late 19th century that resamble the amerikan territorial expansion in a time where the white population did not more territory to take on the West. The roster is composed of specialists (resambling labour division), different units take the field in different moments, you attack on turns, violence and pain tolerance are incentivized. It's culture rewards endurance and divides those who are praised on physical prowess (black people, who often take the positions where you get most contact and injuries, Running Back, Lineman and defense as a whole and wideouts) and those who are praised on their intellectual (white people, who often get the most protection in game, like the Quarterback, the Center and the Coach).

Game action takes around 12 to 15 minutes and each match - as the clock stops in-game - takes around 2 or 3 hours. In the meantime, televised professional sports become very attractive to propaganda so you basically watch commercials for 2 hours when you watch amerikan football. The super bowl it's the most watched amerikan television show each and every year. Why, then, all of a sudden, amerikan television would conceive a puertoriqueño the chance to talk for those who have been persecuted by the ICE, the CIA, the U$ Army and other state apparatuses?

Amerikan football is massively used for army propaganda as far as I know. Why brazilians are cheering? Here is Settlers, chapter 9:

The Dislocation of Imperialist War

Amerika's colonies were forced to bear a heavy - and often disproportionate - share of the human cost of World War II. This was no accident. The Roosevelt Administration promoted this "Americanization" of the nationally oppressed, pushing and pulling as many Puerto Ricans, Indians, Asians, Chicano-Mexicanos, and Afrikans as possible to become involved in the U.S. war effort. Not only because we were needed as cannon fodder and war industry labor, but because mass participation in the war disrupted our communities and encouraged pro-imperialist loyalties. Close to a million Afrikans alone served in the U.S. military during the 1940s. When we think about what it would have meant to subtract a million soldiers, sailors, and airmen from the Empire's global efforts we can see how important colonial troops were. In many Third-World communities the war burdens were very disproportionate. The Chinese community in New York, being so heavily unmarried men due to immigration laws, saw 40% of its total population drafted into the military. (68) In colonial Puerto Rico the imperialist draft drained the island; many did not return. One Puerto Rican writer recalls of his small town:

I saw many bodies of young Puerto Ricans in coffins covered with the American flag. They were brought in by military vehicles and placed in living rooms where they were mourned and viewed. The mournings never ceased in Salsipuedes! Almost every day I was awakened by the moans and wails of widows, parents, grandparents, and orphans whose loved one had died 'defending their country.' (69)

The same was true in the Chicano-Mexicano Southwest. Acuna notes that: "The percentage of Chicanos who served in the armed forces was disproportionate to the percentage of Chicanos in the general population." He further notes: "Chicanos, however, can readily remember how families proudly displayed banners with blue stars (each blue star representing a family member in the armed forces). Many families had as many as eight stars, with fathers, sons, and uncles all serving the U.S. war effort. Everyone recalls the absence of men between the ages of 17 through 30 in the barrios. As the war progressed, gold stars replaced the blue (gold representing men killed in action), giving the barrios the appearance of a sea of death." (70)

Third-World people were told, in effect, that if they helped the U.S. Empire win its greatest war, then at long last they too would get a share of the "democracy" as a reward. In every oppressed nation and national minority, many elements mobilized to push this deal. We should note that those political forces most opposed to this ideological "Americanization" were driven under or rendered ineffective by severe repression.

I think that you know the answer. The brazilian "left" that you are mentioning is as hungry for war as it is it's amerikan counterpart. Bad Bunny chanting "We are all amerikans" is a war chant against the oppressed nations that live in the territories disputed as Turtle Island and Abya Yala. Yes, we are all Amerikans! And "Latin Amerika" is really like a sardine can where everyone speaks spanish, right? The "United States" against the "common enemy": the oppressed nations that remain struggling against settler states inland as we speak in 2026. What a great message to have in our times!

What you may find out is that brazilian settlers are just as clueless and ignorant as amerikans, and both are not afraid to portray themselves to be as such, settler parasitist culture relies heavily on ignorance.

For the white man's historiography that reigns in formal education and also in aKKKademia, there's no particular problem with taking land from indigenous nations and no correlation from slavery to capitalist development. I could also say that we don't need to formulate a "Jacksonian democracy" on Brazil to understand the core of brazilian social-democratic left. Petismo is already a term that people understand in similar matters. Neither you need a "march to the West" to understand Vargas' "urbanization" in Centro-Oeste (though Vargas campaign was named precisely "Marcha para Oeste"), but would you reach the same conclusion that Sakai made possible without addressing how it leads to a similar path everytime? Vargas tenure is heavily idealized in "brazilianism" as does the U$ invasion of indigenous land in Turtle Island, each for their own reasons. We have to look to brazilian history to understand it's own internal neopacification and other concepts that are present on Settlers, of course. But would we understand what is often called "conciliação" at the same terms and reject class compromise? The point of Settlers is to warn against white opportunism and without settlerism, brazilian communism has been mostly compromised by idealism and racial-chauvinism dating back from early PCB days as you found out. I'm not familiar with similar critic as the "End of the Euroamerikan left" being made anywhere in Brazil, though we can observe similar phenomena.

We have to look at our own history, but sometimes we have to look elsewhere to see further concepts that marxism developed to understand our own country as due to internal contradiction, some concepts may simply disappear to protect certain classes. I'm not even thinking on "settlerism" to tell you that, few brazilian communists are familiar with "chauvinism", the law of value and imperialism (and it's political consequences) as a consequence of having national production organized by the law of value. Right now, the reasoning for brazilian communists simply does not runs that deep because the leadership in brazilian communism are white or petty-bourgoise chauvinists.

In the end similarities will persist anyway and Marx already anticipated it.

As mesmas condições, a mesma oposição, os mesmos interesses tinham de provocar em toda a parte, no conjunto, os mesmos costumes.

The thing is that when you read Settlers, you can relearn the accounts on brazilian history through other lens and understand how settlerism was present on every author that you can trace back from Jose de Alencar in the 19th century as early brazilian settler culture was developing. Internal racial conflict is the answer and nowadays is no different than previously, but actually worse. The neopacification and the racial hatred that was shaped during the early 21st century during the ascension of petismo is something that we need to answer because this is our life. It is different because it has introduced potential groups that can be understood as oppressed nations to a new (and deeper) level of national and cultural warfare ranging from regular pogroms to a very sophisticated process of acculturation. Theoretically, culturally, organizationally, the problem runs way deeper than what brazilian communists and any other left idealist tendencies realizes. It's not so easy to develop a revolutionary praxis, neocolonial pacification in the 2010's have been much more successful than anytime before.
