The whole reason “gender identity” is a controversy is that 80%+ of these transgenders are men but less than a quarter have the male plumbing removed - so at least 2/3 of the “transgenders” are biologically intact mentally ill men demanding access to women’s spaces to validate their delusion ... and most retain normal sexuality, stating they are sexually attracted to women, but demand to be seen as lesbians.
