this site has a mechanism for removing players who express hate. Specific references to white supremacy should get players instantly banned. Indeed you find this thing on the internet, but we can be better here.
Also, I am not referring specifically to insults, but to the espousement of certain completely unacceptable worldviews.
Oh so you don't have a problem with players being jackasses, you want to ban people for criminal wrongthink and violating your social justice warrior narrative. That's what I suspected but I didn't want to immediate jump to any conclusions. Now I know that you're a complete idiot.
