If all you want is someone to concede that there are shit heads on all sides, then I'll be the first to do so. But the guy in this video isn't part of antifa and is trolling Fox. Also the Antifa group itself is the far fringe of the left and hasn't been welcomed into the mainstream with open arms like the alt-right has.
Part of the problem of trying to anticipate the response to your post is you look like a complete moron when you don't get that response. I've never compared anyone on here to Hitler, nor have I labeled all conservatives this or that. In fact, there are some very reasonable conservatives here. Sorry that I don't fit into your stereotype of everyone on the left.
