You don’t really buy the idea that trans people are deluded into thinking that they do not have the chromosomes and sex organs that they were born with. I mean come on, that is the whole reason they are trans, is that the reality of their biology, which they fully understand, does not match the reality of their felt gender.
But you can’t be unaware that there is a vocal substrate of the trans community and their supporters who say that every transwoman was born a woman and if she says she’s female she’s female. And if that is too ambiguous, they go on to say that if she is female then everything about her is female, including her XY chromosomes and “male” (my word) genitals. Hence terms like ‘lady-dick.’ “Her penis is female because she is female.” Her muscle mass, lung capacity, Adam’s apple, all female.
