I've done that. Not been banned.

> point out that white supremacist and other hate speech is welcomed so long as it is polite

Well, I mean, aside from being false, that’s also going to often be a specific labelling of something here as “white supremacist” or “hate speech”; flagging exists pretty specifically to deal with content where that description actually applies without sidetracking conversations with incendiary debate about whether it does. So, yeah, comments doing that will be flagged and moderated and, if thet persist, will likely get you banned.

If it was banned, you couldn’t post from it. So, since you obviously can, I assume you are misrepresenting the facts when you call it a banned account.
