Wouldn't got this far. They are as much communists as the skinheads of the 80s were Nazis. They're both just deplorable thugs who would take any cause if it justifies their want for violence and destruction.
I wont dignify this behavior by thinking the have an actual thought process behind their shit that has to do with political and philosophical positions.

To add to this. This is why talking about Antifa is a bit hard. I can fully support the original idea behind Antifa and what they did for a long time, but in recent years they've become a cesspool for vandalists and thugs, and i think they're actually harmful to their original cause.
