If someone says

I am Nazi, heil Hitler. Here is a swastika it is my symbol.

Yes ban them

I think that depends on whether or not that person actually believes that. If it's just low quality edgelord shitpost spamming the community yeah get rid of it, but if this person is actually willing to have a good faith discussion on their ideals I think the conversation being had for better or worse seems preferable to just outright banning/silencing.
