You want to end the anti-FA (First Amendment) it's simple, solve the communist violence of the antifa the way we have always solved issues with masked communist, remove the mask and put them in jail for a long time, give them felony records that they can't weasel out of like and ex-kgb agent, ruin thier stupid lives. 

Antifa want violence, give it to them, end thier future in the most brutal way possible. if 20 or so commies don't go home, then the rest will probably not come back. The other outcome will be what all commie movements end in, massive holocaust
