Communist/Anarchist groups like these have been around for decades, rioting and such.
The civil and cultural war we are in hasn't occurred because of Antifa, it has materialized because the fascist/communist ideologies are now being advocated by a huge number of major institutions and players in America. First they will go for the symbols (statues, etc) to build and propel their movement. Then they will come for you if you won't conform and support.
You are going to have to accept the fact that one half of America isn't American in any true sense of the word.
Man up for god's sake. Get you guns and practice head shots.
