If you mean to ask what would happen if white people took it over? Having been through chaz a few times, the population is overwhelming white (Seattle itself is only ~7% black). Capitol Hill is itself a white, gentrified area.
Or do you mean actual white supremacists? Charleston went down fine without a hitch. I seem to recall our President call them some, “very fine people.” [1] I also don’t recall any police response to the recent armed Michigan courthouse takeover.
I did, however, see multiple beatings and tear gas used against protestors for no reason at peaceful, unarmed protest events.
Maybe you can explain why you out “white supremacists” in quotes? Maybe you could list some recent examples of protestors being “crushed without mercy”? (I can list plenty, but none that are white movements. Please inform me!)
