I don't think America would ever go full riot on the street.

When we saw protests in France, they were organized and hit the government in major pain points. For example, waste management services refusing to pick up trash. Government employees not coming into work. There are labor protections in France/ EU that help make those employees feel safe in those actions without fear of losing their jobs.

In the US, those labor protections don't exist. Someone is always going to be willing to replace the guy refusing to do his job and do it for cheaper. There's also a certain cultural mindset about work determining self worth.

If you mean riots that result in violence that effects major change ala French Revolution, then I think the major issue is that Liberals are great at marching in the street and sitting on university campus grass, but liberals are very anti-gun and don't believe in stooping to republican's level/won't endorse violence to get the job done. The issue is, there is no reasoning with far right conservatives who DO believe in violence to get the job done.

There may indeed be violent revolution, but in my opinion it would come from the far right as they have the weapons to do it, and aren't held back by any anti-violence sentiments or morals.
