You raise good points, but for me the issue is, the Nazis then still have their own bar. And that creates a hub for them to advertise, spread, and sow hatred. And eventually, to try to buy the owners of the media platform. This is the literal "embrace, extend, extinguish" playbook they're using. Is that not a problem too? How could we combat it best?
I think it's better if we shut down their bar and bar them from even coming to any bar.
They want to go to a bar? Either don't be a fascist or shut up.
