I am not sure that MAS is gender critical. The point has been made, when people were trying to make out she's some sort of terf, is that she respects the right of individual beliefs, but that no one belief should take precedent over another.
But on reading the thread, all I kept thinking it that in terms of the law, it only cover around 10,000 holders of GRC.
The vast majority of those insisting on "their" rights are in fact insisting that their life style choice (to no coform to gender stereo types) is the equivilent.
So everyone, whether EHRC, the Supreme Court, are actually misrepresenting the need.
The question is why cant people who are what used to be called "gender benders", behave as "gender benders" did. They didn't demand to use the toilets of the opposite sex, because the whole point was to show that whether you were born male or female, you didn't have to dress, behave or have interests that society told you you should have because of your sex.
In fact this was a far more revolutionary position as it meant men who wore "female" clothes etc., would use men's toilets.
This generation are effectively saying society imposed norms are their goal.
