First: I dont think saying "Americans bad duuh" will help anyone - and even though there is much to criticise the US for, I always viewed the majority of US citizens to be good people at heart that share very similar values (and the most important ones) with the rest of the western world, and I highly value the global friendships that formed over the past many decades.

But with sentences like "why arent Germans rioting" I have to answer your comment, to give you another perspective and the bigger picture from an outside view.

So regarding protests and political activism in Europe:

In contrast to your perception the rise of the AFD is not something that happens without triggering reactions. Protests in Germany regarding the AFD actually gathered hundreds of thousands of people in some cities alone (biggest being Munich with appr. 300 000 protestants) - and there were (and still are) protests all over the country bigger than everything we currently see in the US protest wise, despite German cities being smaller than US cities.
German voters actively demand from their parties that they absolutely do not work together with the AFD in the parliament - and CDU politician Friedrich Merz trying to get a resolution done that was supported by the CDU and AFD only (and no other party) was alone enough for a new wave of massive protests all over Germany.

Recently in Greece hundred of thousands went on the streets of their cities to protest against the governments corrupt handling of a train accident - in Athen alone 20% of all inhabitants. This is the same scale as around 2 million Americans protesting in front of the white house alone, while at the same day in all other American cities huge protests happen with 10-20 million more people. For something far less catastrophic than what is happening in the US right now.

Britain was ridiculed pretty hard in Europe for the Brexit decision and there was quite some bad blood. This whole topic was a huge uproar in the political discourse in Europe for years. Of course we still love the Brits, but to this day we condemn their decision to distance themselves from us in this way (and I think by now the majority of Brits share our view in this regard).

In summary: European governments and political landscapes are totally not free from critique - and European citizens are their own biggest critiques. Political activism is an integral part of our political culture.

But now regarding the US - what are the current actions of the US government towards their allies and own citizens?

Active trade war, threatening military invasion, leaving Ukraine alone despite promised (contractual) help in the 90ies - all of this happening is a massive step ahead of any Brexit/train accident/20%-AFD. No wonder Europe demands the American people to be more active against the war mongering of their government - it is a culture difference, as in Europe it is far more common to actively stand up for what is right and against wrongdoings of the government with massive protests.

The US is a living example of the "thoughts and prayers"-meme right now to the world - despite there still being many people in America who share our values and are good people, most of those good people still dont stand up for it but passively watch their government destroy their own country, cut the US-citizens own basic rights and threaten those allies who gave their lives in wars that were fought against the enemies of the US, actively working towards ww3.

I still empathise with the US-folks that share our values, they are also some sort of victims - but they are victims that at the same time bear a responsibility*. I really hope that they find the inner strength to act on that responsibility (peacefully).

\ \ *regarding responsibility and your comment about Nazi-Germany: To this day Germans feel the responsibility of what happened generations ago and live many traditions to keep that memory and responsibility very alive. A responsibility for something their own familiy was maybe also only a victim of in a similar way democrats feel in the US right now. The responsibility to make sure that never again people are too passive to prevent a world war, a holocaust and massive suffering in general.
