But the surgery is just an illusion, you and they are assuming that the surgery will make them happy. When they can't know what it will feel like before hand and the procedure is ireversable. If you had a forced sex change surgery and then had corective sugery to do the best surgons could do to restore your form I am 99% sure that you would be unhappy with the result. You as a person would be un happy with the equivalent transgender body.
Many people do regret the surgery and kill themselfs, but you don't need to take anyones word for it. We can use logic if we are using feelings over logic we are doomed to go extinct soon and it dosen't mean anything. You can't turly want what you don't known if a man thinks he wants a female body he wants something that he can't have he will never have a real female body and he will not know what it is like before hand. He may want to be treated like a women and surgery can fix that, but is it worth risking that and then regret it and commit suicide? Are you encoreging pepole to do something that can likely results in their death?
Doing almost anything can result in death. There are plenty more people who have had a sex change an came out happy than people who haven't. If they think it's worth that risk, more power to them.
Well, this is new.
