The irony is that if these AZs were permitted it could give said segregationists exactly what they had been after for decades.
In terms of declaring themselves "autonomous", I'm thinking (and I imagine others in power are thinking as well) that this is simply done as a statement of protest, rather than an actual serious attempt to form a sovereign government. So crushing this without mercy is politically infeasable, especially given that the whole protest is about police and justice reform. I don't think this sets any kind of legal precedent. Better let them make the statement and let it run its course on its own.
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!)

Like this scenario in 2016 that ended when the last far-right occupiers of a national wildlife refugee left after 6 weeks?.
