I've been hearing quite a bit about them lately, so could anybody tell me who they are and what they really stand for? A quick Google brought up a lot of talk about ties to communism. Are there any Antifa members on here who would like to clarify things?

I also noticed this on Wikipedia - https://en.m.wikipedia.org/wiki/Antifa_(United_States)

"As of June 2017, the Department of Homeland Security in New Jersey lists Antifa as a domestic terrorist group, claiming that they "incite violence." Members of the group have defended acts of violence committed by other members."
