Asking platforms to not host and promote violent and racist content is hardly censorship.
Allowing violent people to post online is fine. Allowing them to post violent content is bad. I don't care who the person is. I care what they post. As long as they're not advocating harm to a specific person or group of people it's fine.
I'm okay with people saying racist things from a free speech perspective (it's still despicable). I'm not okay with them saying people should go burn down the synagogue in downtown Seattle.
I've done a bit of volunteer work as a censor (moderator) and I'm not opposed to censorship. A flippant/morally self-righteous attitude towards censorship is a red flag though.
