Compassion and solidarity should not be imposed without compassion, though. You don’t fight hate and oppression with more hate and oppression. When most people are annoyed with in-your-face militant attitudes it’s not because they don’t want to be nice. It’s because they don’t want to be bullied into following the dogma of the day. Of course you also have plain old racists, but putting them in the same bag as the big chunk of the population who just wants to get on with their day is bound to alienate quite a few people. Hence the blowback.
When someone explains that I cannot not be racist because I have pale skin (which does happen), well it just makes me want to punch them in the face. If we are supposed to all belong and accept each other regardless of our external appearance, then people making assumption about me based on it is just prejudice.
