You've said that transgender must be psychological because you know 35 people who have all grown up happy and normal. Do you? If you'd met me (and maybe you did) 15 years ago you would have seen someone happy and normal (and fertile, since you seem to associate have children with being normal and happy). That's what I showed to people. That's how I behaved. Then I decided I could no longer go on living someone else's life and I made some major changes - not the same as Mauvepink, but still major.
As other people have said, you don't know what you are talking about. If you want to, you can find out what transgender means. If you prefer, you can continue in your happy ignorance. That's your choice, as my choice of how I live is mine.
As for your belief that children are forced into pretending to a gender other than their apparent biological gender, you are wrong, desperately wrong. You are wrong about their parents, wrong about them and very damaging.
Sort out your own life, you've given us enough clues over the years. You can't solve your problems by attacking innocent bystanders.
