What is wrong with haters?

So i have read various articles where some people are complaining that Brendan Fraser shouldn't be in that role in The Whale because he isn't actually gay or fat. So they should maybe get a bad actor because he is actually fat and gay? Stupid!

He is a fine actor who was willing to get much fatter and play the role of a gay man and have his sexuality come into question...and haters had to complain. So only real vampires are supposed to play them in the movies? How about gangsters? should only real gangsters play gangsters in the movies?

I am sick to death of hearing stupid complaints about comedians who never said anything racists to begin with ...get fired from life because she made an observation...(Roseanne). or ludicrous debates over which sex or color of an actor should be to play a role when it doesn't matter.

it isn't as though someone said that Bieber should play Black Panther...
