The tragic irony is that if you just keep "man" and "woman" as simple sex labels, misgendering is not a possibility.
It is only when you decide "man" and "woman" are personality labels that you create the risk of "misgendering".
Do you see? It is trans people's idea that "man" or "woman" can be something other than the body in the first place that creates the problems they complain about.
Put bluntly, it's only their own sexist projections about how other people feel that makes them feel they are not the right sex for their sex. They literally invent the problem for themselves by insisting sex mean more than it actually does.
Female people exist. Being pregnant is something only available to female people. While not all female people can or will become pregnant, nevertheless you can broadly define female people as people who one cannot say for certain will never be pregnant based on a simple visual check at birth. And everything else, the gender, the social differences - those all follow from that.
It makes no sense at all to say we need a label, and separate spaces, and protected rights, for people who feel a certain undefined way that not only can we not agree on but we cant even agree everyone feels it, but we don't need a label for the half of humanity that is physically female.
If we actually somehow really didn't have the word "woman" meaning adult human female, if we were really in a world where the word had never existed, we'd have invented it pretty damn quickly!
It's only because we are in a world where the word does exist, where we do all understand it but are supposed to pretend we think it means something else (while having the original meaning hanging around in the background to underpin that new defintion) that Generists have the luxury of pretending they don't think we need to recognise the two sexes in law, language or society.
