While the majority of people in those groups may be peaceful in their actions, they are following ideas that lead directly to the harm of other people, which is reason enough to stand up against them. Antifa at its core does not pursuit to bring harm to any human being. It's sad that some people misuse Antifa for that, but the idea behind it is still a good thing. At least in my opinion. I can't say that about neo-nazis, KKK or white supremacists.
I will happily condemn these actions of those individuals. But I can only speak for myself. I did nothing to defend it in any way. The only thing I defended was the idea behind Antifa. And for the record, yes, I consider myself to be part of Antifa. I participated in a lot of actions against the german parties AfD and NPD around here. They were all peaceful and nobody was harmed.
Cares to post sources for the massive condemnation of Antifa bad actions by several Antifa peacefull people in public spaces?
