Preens - I used the colonialism metaphor on here donkeys years ago.
But yes Michael doesn't seem to be connecting the dots. Me being female is a contingent fact about my reproductive biology. In a perfect world it shouldn't matter to other people's views about my personhood and humanity.
But historically that contingent fact about my reproductive biology has been weaponised against me, used to define me as other and lesser.
So when some men, aided and abetted by some women, try to redefine "woman" to include "men" this is both an ontologically incorrect move and also a political landgrab which seeks to make the voices of the oppressor class the loudest ones within any political movement founded by and for the oppressed class.
The ontological mistake is annoying in its stupidity. (Like including blue eyed people in the class of brown eyed people, or hamsters in the class of birds).
But it matters deeply and profoundly, with huge real world consequences (free versus compelled speech, freedom of association, the human right to be incarcerated only after due process and only with members of your own sex, the continued existence of women's sports) because of the political aspects.
