That's a random grouping... hate speech, incels, pornography, and transgender people? You really see all of those as equally in need of banning or censorship?
Meanwhile... I think anyone running a forum can censor or ban as they wish. In the USA, for example, you are supposed to have the right to free speech as it pertains to government restrictions... but you don't have the right to come into my house and say whatever you want. Neither do I have the right to come into your house and say whatever I want. Just in public is where we have the rights.
Now, I prefer open conversation where anyone can say whatever they want. This includes hateful things. I support that freedom because IF you start drawing a line, then everyone gets to draw a line... and your post is a good example where it seems like you want to be against hate speech but also against transgender people in general which is accidentally the perfect example of why censorship gets out of hand in a hurry.
Ban the most awful thing you can imagine and most will not bat an eye... ban the next worst thing and you still get lots of support... eventually you're going to keep moving that goalpost to something most do not agree with, but so much has been banned there will be not many left to oppose you.
I always say let the horrible people say the horrible things out loud so we know who they are. I'd rather know you are horrible than you be secretly horrible because you've been banned from talking.
