You are defending Gab, and the literal nazis that use the platform to openly talk about genocide and committing hate crimes.
We did shut down the nazi ideaology in WW2, and it did not 'progress to the point where anyone they dislike for any reason will be silenced'. Your assertion is not based in reality.
It's happening in the US right now with people having their lives ruined for wrongthink, even if it's completely unrelated to Nazism. If you're too blind to see it then it's not my problem.
