The twitterati have sniffed out the fact that he's (probably) conservative or libertarian. That's sacrilege in hollywood. They want the actors to appear to be super progessive (which most of them naturally are anyway, as most people in "the arts" are), because it's very helpful in distracting attention from the fact that it's the most capitalist and unequal place in the entire country.

It's a lot easier to wheel out some actors to explain that climate change and racism are bad, instead of actually changing their own local economy to help benefit more people instead of just a tiny handful of super millionaires and billionaires.
