Speech should never be policed; instead, speech that is repugnant gets shut down by peers, usually by not inviting them or whispering behind their backs.

You don't need violence or suppression or censorship to stop speech like that, you just walk away from people who say things you don't like if you aren't willing to make the effort to change their minds in a healthy and reasonable way.

Eventually they get the picture that people don't like what they're saying, and they are presented with a choice to chill out with that stuff or keep going and risk friends, family and strangers disapproving.

Regardless, "hate" speech is protected under the first amendment, and any government official in any capacity even advocating for it should be removed from their position and cast out from the country.
