“Whitesplaining” is my term for when white people try to explain racism. Not necessarily explaining away racism — they are usually acknowledging its existence and are condemning it — but they are acting as though they understand racism. Yes, it’s like mansplaining.
Here’s an example of what I mean. I won’t mention any names to protect the innocent, but I was participating in a meeting discussing a paper written by a Black philosopher. The Black philosopher’s topic was race relations and the symposium participants were all white university philosophers, mostly professors with a few PhD students.
