(b) Indeed seems to be the objection. "But we are a diverse group of people. It is unfair to categorise us all under a single term, unlike saying all trans people are trans, or gay people are gay. Especially I dislike being classed in the same group as those who oppress and try to control you" is about the distilled version of what I interpreted from reading that thread. Which is not new. And the person he was calling 'good' made a follow-up post about terminology and how she does not identify with labels like 'straight' and would prefer to be thought of as just a person. Sometimes I wonder if this is some kind of elaborate, satirical prank.
