I personally don't see a big contradiction between calling for a more diverse understanding while pointing out that what is nominally "normal" is part of a very specific dominant cultural segment.

And given that the term originated among sociologists, some of them WASPs themselves, I think calling it "unquestionably slang" is strong. Ditto "offensive". If you're offended, you can just say, "I'm offended" without trying to cast it as some sort of false objectivity.
