I think only the crazies (like what happened in the Capitol riot) will come out again. American's are not organized enough to do any real damage. Plus, they're divided over many, many issues you kinda need more than an 80 year old obese rich golfer to fight over. There's probably less than 500 loonies(with horns, painted faces, fur coonskin caps)that will lash out when Trump loses.
The only way to organize American's into fighting/rioting en masse' will be when they are so downtrodden they simply have no other choice, probably about 5 or 10 years away.
