Who's "we"? I in fact can believe that Portland government and community is not fascism. You seem to be the one who can't believe it's not fascism. You seem to be assuming that if people were rioting, vandalizing, firing, looting in downtown Portland, then it must have been justified by
the fascist policies of that city.
The truth is much simpler, stupider, and more depressing: Rioters in Portland don't commit political violence in response to fascism. They cry "fasicsm" to excuse gratuitious vandalism under the banner of political violence.
I've lived in Portland for almost ten years. I have direct experience of how militant leftists behave on their home turf. 2020 was the high point of "anti-fascist" political violence in the city. I think it provides a very useful and eye-opening picture of the "anti-fascist" movement.
