Did I miss a comment? The one I looked at did not say that. It just said voting is a good idea. I also did not see where they called anti-electoralists neo-Nazis. If that's the reason they got banned it would make more sense.
But I was mainly sniping your tirade because we're not supposed to be arguing with the comment here, we're supposed to be discussing the rules and whether OP deserved to be banned. Whether we agree with them isn't super relevant--although I guess it can be if we want to discuss whether given rules have merit or not, so maybe there is some gray area.
