I don’t think so, but if it were, then Jordan Peterson has just announced that he is trans.
Either that, or he is a liar.
It is most weird how some people get worked up over a simple, non-judgmental descriptor. There is no opprobrium attached to being cis — in fact, it’s a social advantage. So what has got these people irate?
Maybe it’s the implicit acknowledgment that if cis people exist, then trans people do, too.
