Kid, you aren't "winning" this debate and I believe understanding why that is, is going to help you a lot in life.
This is not a game, there are no rules and referees (other than the forum rules but that's a separate matter) in this. You don't score points or win anything by trying to get a "gotcha" out of people. Most importantly, no matter how well you write your comments, no matter how many people you have helping you find articles that defend the indefensible, you can't "win" by trying to argue that up is down.
This is real life debate and there are only two things that matter: a) can you make people believe that you are correct? b) what is the correct answer to the debated issue?
For the first part, you haven't convinced anyone that Nazis are the real victims that need protection or that Antifa is somehow really, really bad. For the latter part the answer is pretty much the same, Nazis bad, Antifa hooligans who band together because they don't like Nazis.
And here's another thing: We don't really care about making you admit "defeat" either. This isn't a game for us. When we see someone jump in to defend Nazis and fictional Nazis and complain about people who oppose Nazis we get upset because that's a pretty shitty thing to do. If it looks like everyone is ganging up on you it's just because there's no one else here who uses every single excuse to defend Nazis.
Heck, I've talked about non-violence before when some folks (*cough* Niam *cough) go over board, but even I know that Nazis are the real villains here.
And as another person who would get a bullet in the head if they take charge this is not an idle topic. In fact, simply as a person who opposes genocides I take personal interest in the "should Nazis be allowed to freely preach their hate and gain political power" matters.
EDIT:
Right from the Fascist-horse's mouth: They do not care about free-speech and are only using it as a tool.
