It's, like, the least of the problems, but the discussion around this story once again illustrated why we don't call everyone "them" all the time. The girl he groomed, Takata, also indentifies as they (it seems), so on ree there were texts like "After what they did to them, they need to cut all ties with them publicly" where 'they' were either Ezra, Takata or WB. Sure, sometimes all parties in story have the same pronoun, but in this case 'she', 'he', 'they' would make conversations much clearer.
Anyway, Ezra Miller is a dude. He also claims to be reincarnation of Jesus Christ - we can't prove scientifically that he is not, but we can prove that he's a dude.
I don't think people should lose their job for wrongthink - but in this case, dude is using his fame and wealth to groom, harass and abuse teenagers, the more he's promoted, the easier his hunt will be - it is actually important for common good that he's no longer the face of major all audiences movie.
