Seems like a really bad idea to give swaths of people a common enemy and then taking away the thing that prevents them from feeling like they have nothing left to lose.
Honestly IMO the big threat to them comes from the right. They've spent a generation cultivating violence and gun culture in their own followers.
I think it's an accident, but not a surprise, that the recent Trump assaignation attempts were all right wing. The left has no monopoly on ADHD and depression diagnoses. And they teach their folks conspiracy thinking.
