Well, I applaud their honesty. They may be bonkers, but they do at least have the merit of being logically consistent (if you accept their totally bonkers starting position).
Because if TWAW, and self ID is the only criterion by which to decide whether someone is a woman, then, yes, logically, if you accept those two premises, Jacinta Brooks is every bit as much a woman as Pips Bunce, AllieLia, me, Mother Theresa...
Or alternatively, if you reject those two premises, and instead take biology to be the defining criterion, then three of the above list are not women, and two are.
I know which view I hold.
