I'm not sure it does. Many of them have the same likes and behaviours after as before. I think Caitlyn Jenner is something of an anomaly in her love of fluffy female things--I can't explain it and it does unsettle me, especially after you've already lived as a white male celebrity . . . wow if you wanna pose on Vogue in your pink baby dolls, go ahead but don't ask me to get excited about it, even if I will stick up for your rights. I understand what you're saying, and I think the categories of male and female do NOT, in fact, necessarily align with any behaviours except those that are culturally conditioned. We cannot underestimate its influence. As sexes we apparently are different in size and strength, aggression, and nature of sexual arousal. After that, it's a giant toss-up. There is NO theory of personality based on gender. But something is happening in the brains of the transgendered that makes them perceive themselves as the other sex.
