But...
No one is saying you CAN'T play those people - what they're saying is maybe you should take a step back, check your privilege and pass the baton to a fellow actor from that group of ACTUAL HUMANS and give them a chance.
But if you've been handed a role that's telling someone else's story and a million actors who could tell it EVEN BETTER were ignored in the process - that's not OK.
Peace ✌️
