BRHood: Is the person themselves a PoC? That’s the only reason where it may be. If they’re white like you are, then it’s not overstepping at all but doing your job as an ally. if they are a PoC, I would advise telling them that YOU’VE been told it’s problematic and point them to sources so they can educate themselves.
I've tried to convince somebody that brownfacing or blackfacing is not okay, ever, but at the same time, I feel like I'm stepping beyond my boundaries, as I'm not a POC, and I don't really know what's considered acceptable and not, in terms of white people and trying to talk about racism. Odd question, yes, but what do you think is overstepping?
