Adding a content warning to the account/post seems about right to me. Someone that creates an account just to immediately post something like this is very likely not following the community guidelines. It's not like it was posted with any research, or as an opinion, or even on a thread on that topic. It's unlikely to have been posted with any altruistic intentions. It's much more likely to have been posted from a base of hate and with the intent to cause harm. Heck, that you have an issue with this and think that it is 'extreme censorship' makes me much more likely to be suspect of your intention behind future posts here. That you frame this action as being 'banned' when the account wasn't actually banned only adds to that.
