And in reality, that is essentially correct.

Insofar as "TERF" has basically just come to mean "literally anyone who doesn't uncritically swallow our ideology hook, line and sinker (HOW DARE THEY!!)", that is inevitably going to encompass an absolutely huge and extremely diverse set of people. Men and women; gay, straight and bi; of all nationalities, skin-colours, and religious backgrounds; and across the political spectrum.

They wanted "TERF" to use as a handy pejorative against anyone who disagreed with them. Well, now everyone's a TERF, because the vast majority of people the world over disagree with them. They're playing it for now (trying to "smear" conservative people as radical lefties and "smear" left-leaning people as radical conservatives, for example), but the truth is that this development is, in the longer term, very very bad for the TRA Bandwagon, as it is becoming harder and harder to hide the fact that concerns over their behaviour is almost universal in the real world.
