People weren’t being deliberately destroyed at the early stages when Kristallnacht occurred either. I believe that’s the reasoning behind why prominent activists and lawmakers (rightly or wrongly) compared federal actions in Portland to the Nazi Gestapo and such a comparison wasn’t seen as offensive and they weren’t cancelled. The idea of recognizing warning signs.

For the record, I’m Jewish and don’t see such comparisons as offensive. It’s good to try to learn from historical similarities, however faint.
