Calling ace people "het" in 'cishet' isn't right, same as calling a cisbi person a cishet if they're not hooking up with people of the same gender, for whatever reason.

Calling ace people 'het' in 'cishet' is a line I've heard cishet aces use; heteroromantic, asexual. This was what was in mind here; cishet ace people, who face no (so far as I'm aware) material oppression hijacking queer spaces and repressing queer voices.
