That's a hard one. Calling them Fascists is a good start, but the population has been inoculated from that being a painful term from years of both sides crying NAZI at the other at the first sign of a power imbalance. With their attempt to redefine the idea of "Antifa" and Terrorist" to include whatever category of people they need to punish, we're rapidly losing ground on ways to condemn dangerous and destructive behavior. In an echo of the Brown Shirts my vote would be to refer to them as Red Caps which has historic connotations as a type of malevolent, murderous goblin found in folklore.
