so then i guess my IQ doesn't define my intelligence, my physique doesn't define my fitness and health, and my semen doesn't define my child, right?
as awful as all of these brown townogies are, the last one is particularly bad for your point. first of all, a single sperm cell is probably what you're thinking of. and even when you use the right words, it still doesn't "define" the child, a child is the combination of two cells, and after being born it is defined far more by experiences than the fact that your sperm cell was used to create it
gender is psychological, not physical
and while we're asking questions, why do you care? like, what effect does it have on you for people to be of a different gender than you want them to be?
