The concept of intersectionality was invented by a black woman who definitely has never had any problem pointing out how black men can oppress black women. Nobody wielding the concept need have any discomfort pointing this out. So I don't think anyone has any idea what point you're making here with the repeated innuendo.
If you were hoping to suggest that intersectionality does not allow black people to be considered oppressors, that's just a right-wing caricature of the concept. You should read about intersectionality from sources that actually describe the concept accurately, rather than ones that merely want to sneer at it.
You promote bad, inauthentic uses of the concept because you want the concept to fail. Why you want the concept to fail is left as a trivial exercise for the reader.
The blind spot I posited and which you then summarily demonstrated.
