If you go to certain left wing rallies, they WILL show up. I have seen real live nazis screaming at my friends at an anti-ICE rally.
The problem with these guys is they do have a narrative that is appealing to a certain set of people about nationalism and certain ethnic enemies that care creating the problems. The idea is to prevent their growth and flourishing because if you see them get very common, we are in deep trouble... though given the debate tonight with the president signaling "Stand Back. Stand By." to the Proud Boys, I sense a creeping darkness.
I'm not from around there, and it isn't my business to defend nor condemn it. I do think taking it as ipso facto evidence of white supremacy is a Yankee mistake.

Edit: I did see some confederate flags being flown in middle of nowhere Mississippi, but I honestly believe they're not flown as a symbol of hatred (at least not always) as some people had banners next to their flags saying things like "Pride not hate", or the rainbow flag, or other phrases trying to distance themselves from the negative connotations of the flag.
