If it was about body distress, cross dressing wouldnt help.
If it was about personal happiness, preferred pronouns wouldn't be an issue.
Whatever trans is, a four year old, a teen girl, and adult men do not have the same motivations, the same demands and the same impact on others.
The fact is, adult men start by cross dressing at home, then with friends, then in public. Surgery and drugs arent the first stage and more often than not, aren't a stage at all.
So whatever trans is to these adult men, everyone else is having to cope with transvestism. Just men wearing womens clothes, but demanding PP, to be called womens names, to see themselves as the most oppressed, the most marginalised and the most in need.
