How is it compatible with “living as a man” to do literally the most female thing possible?
As far as I can figure out, this is to do with what keeps being called biological essentialism.
The sense of inner identity creates the reality the person speaks as their sex (where the intended meaning of the words sex and gender appear to have become too confused for me to work out, so my apologies if I have this wrong) rather than the biology of the body. So the idea would seem to be anyone in any biology can be anything depending on how they feel.
Which I struggle to understand too, as surely that means the same as what gender critical women have been saying for decades - anyone can make any choices and live any way they want regardless of their born sex, free of stereotypes?
And to state that you are a sex you are not, and this be important, but have done something that sex cannot biologically do, would seem in turn to be creating the idea of binary sex being extremely important which contradicts much of what we're told about sex being a social construct/no such thing as a biological male or female/ sex being a spectrum?
The thing is, the impulse to understand is to try to work out and follow the logic. I think this is based again in feelings create reality, not objective fact; which is always going to conflict as objective fact is necessary for shared meaning.
All we have really is that some female people would prefer to be called men and for language to be used according to their preferences to support them in this. Which is fine. The issue is when it is felt that all female people must have their language and reality hidden to avoid offending.
