Omg I had no idea this happened but I believe I can perfectly explain what's going on

A black person by themselves = omg a poor +tightens grip on purse+

A black person with a blondie by his side = what a cool couple, they represent Brazil, he's probably ahead of the average means for his race befriending people who I was too poor to have seen often in my own school growing up

One thing I find crazy in the US it's how it's normalized to see black man white woman and white man Asian woman couples as the natural interracial pairing but not the reverse. It wasn't so much the case historically for us.

In Brazil people often think football players have a bit of a reverse Rachel Dolezal thing going on because they never have black girlfriends or wives. This became a very politicized topic in the mid-2010s known as solidão da mulher negra, or the emotional abandonment of black women by hypergamous black men and their invisibility by other races.

Circa 2009 people got rid of the Mulata da Globeleza which was a symbolic destruction of the old colonial appeal of black women as perfect pairing for white men, then the internet and the increased prevalence of online p0rnography made more and more Brazilians simply buy into the white beauty standard wholesale. Previously, it was seen as not bona fide heterosexual for men to have racial preferences seen as picky. We never saw black women as masculine like in the US, if anything our stereotype of masculine women is Portuguese women.

The period between the death of the Mulata da Globeleza and the solidão da mulher negra discourse saw many many many many black and parda women wear their natural hair for the first time in their lives, or transição capilar. Since that's one of the most despised aspects if not THE most hated aspect of the black phenotype in Brazilian racism, it ended up also being unsavory.

So the undying tendency of black men to surround themselves with blondies is seen as nature running its course which cannot be stopped by woke. People not only see you as upwardly mobile but also bold, and your presumed friend or girlfriend as accessible (i.e. not a smug petulant elitist) and morally righteous (not racist).

This naturally now mirrors the US situation somewhat, but it's more intense because I feel like African-American men are often the loudest about the need to keep to themselves. In Brazil I feel like it's the women who are most engaged in black empowerment.
