This. Go take your boner for GAFs supposed suppression of Freedom of Speech and employ it somewhere like The_Donald or 4chan where it can be of some genuine use to humanity; instead of finding the one corner of the gaming forum world that's actually a bit liberal and wagging your finger at it. If you really cared about FOS that much you certainly wouldnt be HERE of all places attempting to plant your flag.
I do that. I wasted a good share of my life debating right wing people on all kinds of topic.
No one is blocking JonTron opinions, he's free to make them, he's not free to walk over their opinions without consequences. Be on a forum, be on a social platform, your opinions are going to have a consequence. If JonTron were defending human rights or women equality and then he was fired from YL for that, we could have a problem, but as society we agreed (well more or less) that equality is good and racism and xenophobia is bad.
So when JT exposes his extreme racist views, with vile, deshumanizing ideals made up of straight up lies and society reacts to it, is not a bad thing. And is not a bad thing he faces consequences for it.
And racism is not up to debate.
Ought is not is.
Racism ought not be up to debate because humans should be better than that. But we aren't, therefore it is.
Americans are racists. Therefore racism is a topic.
