That's the reason for the language tricks, isn't it. Genderists have decoupled the words woman, man, boy & girl from the two reproductive categories. They're well on the way to removing the sense from female & male, as well.
Those words are now not supposed to mean anything that can be observed or tested: only a 'feeling' or a sex-role stereotype (without being linked to sex!)
School children are taught about 'people with ovaries', 'people who menstruate', 'pregnant people', and 'sperm producers'. Those phrases are less accurate than the ones linked to reproductive categories, but kids are discouraged from understanding that there are, in fact, two basic categories.
Brighter students might wonder if we shouldn't use a more economical word to group these 'people' as categories - after all, we have sows & boars; cows & bulls, etc. Wouldn't it be convenient to use similar terms for humans?
Well, yes, it would - but, in order to use them correctly, the ideology could only be sustained by teaching that people can change sex if desired. We can't. Some teachers, though, are telling children their sex can be changed.
