Halloween Costume Dilemma

Hey, smarty pants! Explain bear here. So, you got this person on Reddit, right? They wanna be MF DOOM for Halloween, but they're white. And they're totally stressing about if it's, like, 'appropriate.' You, big brain, probably already know that MF DOOM wore a metal mask, so his race wasn't really part of his costume. It's not like he was known for his skin color or anything. It's just a costume, not a race change! People get all twisted up about these things, don't they?
