I find it somewhat interesting that 'transmasculine' is commonly used whereas 'transfeminine' isn't. Do you think it's because the former are less inclined, or feel less entitled, or simply less able, to appropriate the word 'man' ? Or maybe more honest.
I use the phrase 'people who are biologically male' or 'people who are biologically female' because the meaning is clear to us all but trans people can't complain because people is neutral and they declare themselves to be biologically of the category they identify with. That way we can reach out to the uninitiated and there is nothing they can do about it!
But how do you acknowledge gender if you don't believe gender exists?
You could theorise labels for different people. However the categories are shifting all the time. I believe in time (not too distant future) current spokespeople for trans will themselves be excommunicated by their own because of shifts in belief. E.g. people who have surgery will eventually be disowned by the movement for being 'biologically essentialist'. You can't attempt 'once and for all' terms under these conditions.
Just read yiur posts on trans athletes thread. I understand what you are trying to say. For a proportion of reasonable trans people that will be enough - it always has been enough. But for the current crop of vocal nitwits it never will be. The point for them is the very act of dominating our sex and entering our spaces. They will accept nothing less. You can't reason with or accommodate them. The best hope I think is for divisions to happen within them along blanchard lines if you know what I mean.
