They aren't obligated to nominate a black person at every Oscar on race alone. I haven't seen every movie this year, nor do I pretend to have, but I genuinely don't remember any black people in roles that had a lot of Oscar buzz this year, let alone any blatantly bait-y roles. Tho if I'm wrong, I'm happy to have someone correct me
Honestly, these protests just hurt causes. Did the Oscars nominate any LGBT, Asian, Latina, etc. people last year and this year? Anyone with any kind of mental disorder? Any children? (I haven't checked, so again, correct me if in wrong) No? Wow! They must hate all LGBT, Asian, Latina people, all people with mental disorders, and all children. Or maybe no one in said groups was Oscar worthy this year. It happens
You could argue Hollywood's racist casting people discriminated and took their chances away, but that's still not the Oscar's fault (tho it's very possibly true)
