They have to know how silly they look, right?
I mean, imagine you are hosting a street party and everyone in your neighborhood is invited. A guy shows up and quickly starts making a nuisance of himself, insulting the other guests, blabbering about how everyone is too sensitive these days, and generally just making everyone else angry and uncomfortable. So, as the host, you tell him to tone it down or you'll ask him to leave. Of course he decides to call your bluff, maybe to save face, or maybe he's hoping that others at the party will take his side. So he ignores your warnings, and you show him the door. He bellows "Help help, I'm being repressed! Censorship!!! I didn't say "Cancel Culture," I said "Mothballed Society" and that's technically not against the rules so you can't make me leave!!! What's the matter can't you 'ice crystals' take a joke?!?!" and so forth, as you drag him to his car.
I'm sure they see themselves differently, but the lasting impression they've made to everyone at the party isn't a good one. Everyone at the party is going to go home and tell everyone else about That Guy who made a fool of himself, and That Guy won't be invited to the next block party. Somehow, That Guy is always shocked and hurt by this. How does he not know how foolish he looks?
