Antifa is not just anti-facism. If you go to any of their rallies or counter protests you'll find most are socio-anarchists or communists who don't see anything wrong with violence.

Ask yourself who is defending the counter protestors when the police are defending the white supremacists, kkk, and other assorted fascists.

Historically the police have a poor track record when it comes to choosing sides in the fight against fascism

If you think antifa has too many anarchists and communists, maybe it's time to mask up and help

Go for it but if you're burning down innocents in your mad dash to stop nazis.

Don't expect sympathy.

While many antifa are anarchists or anti-capitalists, the defining feature is opposing fascism. Don't succumb to a trivializing caricature of antifa as being primarily about wanton violence against property.
