Apart from the valid things that have already been mentioned in this thread: police violence in the USA is a thing. Hell, you can get shot for helping a fellow protestor. Yes I know, police != ICE, but if a real riot breaks out, I can imagine sending in the most ruthless (and psychopatically trigger-happy) shock troops to quell them.

Folks in the US are both comfortable enough and unsteady enough that they will not move. It was Zizek about a week back who said it, people are not desperate enough yet to get to this stage. *** sniff! ***

US doesn't have a social safety net for people to fall back on. So people here can't afford to lose their jobs by being out protesting for weeks.

They don't even reach all of Europe

Why would European riots/protests spill over to America? That's not how this works.

Americans have been protesting. Rioting, not so much. Those are much more rare in the US than France.

Mass movements spring from the ground up, and the American working class quite famously doesn't see themselves as part of the global working class. Solidarity protests are few and far between.

Americans when their country is overrun by fascists:

If things go how a lot are thinking they’ll go, early this week sometime ideally.

There is no reason to think that would happen

50 years.

They are waiting to be rescued by the Europeans. They will await, with the guns beside them.

Depends if they come by boat or by plane.

The US had the perfect opportunity on Halloween with the "de Flock" movement and that appears to have gone nowhere.

You have to understand the cultural context translated between countries.

When the french protest and riot and burn shit, that is the French cultural language of protest, a thinly veiled threat that the state is only in charge as long as the public gives it a mandate. If push comes to shove, the public can always find a new state to run things. They evoke the spirit of the French Revolution as a core message. It says "we did it last time, and if you force us, we'll do it again."

Translating this to the American context, when the government became so corrupt that a Pedophile and convicted serial rapist and fraudster and his band of merry fascists and techno-trillionaires threaten the very foundation of American society, Americans do what they are culturally programed to do. They shoot up a school full of innocent children because deep down they know their culture has no future worth living and it should end out of mercy for future generations. It says "We are cowards for allowing this monstrosity to exist and it doesn't deserve to be experienced by anyone.".

Understood in this light, they have been protesting for years and years with escalating ferocity.
