Gab may have a large number of alt-right conspiracy nuts, but they also have a lot of users who rightfully mock those nutty people. It really is a platform for pure free speech. Unfortunately, its polarization was inevitable as Twitter and Reddit started cracking down on far-right users, leaving only pure free speech websites left for the crazies. But suggesting the website itself condones violence or sympathizes with neo-Nazis isn't accurate.
Per tptacek's comments, the founder does appear to be an asshole, but that doesn't make him a neo-Nazi.
Ok, I didn't see these. You're right. Whoever controls that Twitter account is definitely very alt-right and possibly sympathizes with Nazis. I take back what I said.
I don't know what "neo-Nazi" means to you, but if you'd like, we can refine our terminology and simply talk about "white supremacists and anti-Semites", at which point if will become very difficult for you to argue that the site doesn't "condone or sympathize with" those forces.
