I would like to (tentatively) go to bat for lukewarm progressive celebrities by saying this: They're not actually people.
By that, I mean that they don't really go through introspection and truly think about the shit that they peddle. They live in a miasma of political gas, and they passively huff it while going about their day. Their peers pass luxury beliefs around like cocktails and they never have to deal with the consequences. Maybe they even have a queer friend - they certainly don't have an actively conservative one, since that is the realm of hysterical boomers. They have political takes, sure, but they're the same ones regurgitated by their environment - nothing new, nothing brave, nothing sparked by a complex inner self. It's like when a dog barks at you when you walk by - there is no malice, only stupidity.
Then again, maybe Radcliffe has been uniquely belligerent and I'm simply unaware of his antics.
