It isn't quite the same thing. There is a difference between trying to empower historically marginalized groups, and trying to re-subjugate historically marginalized groups.

Not really. It's all language games.

This is just the mirror image of the liberal conceit they can magically change reality by forcing people to use different words or over-elevating some story (old or new) for ideological reasons.

The lesson from this is that it's all stupid, not just my-side's version, and it should stop.
