On the contrary, I've been traveling across the US quite a bit over the last several months, from New England, the PNW, and the South. While I've seen plenty of signs and a few rallies supporting BLM and other progressive causes, I've yet to see, in person, a single sign or rally or any supportive material for white supremacy. I hear about it a lot on the internet but from my travels anyway I haven't seen it yet.
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.
