I understand you have your opinion, thank you for posing it respectfully. There are large suicide rates in the transgender community sadly, mainly due however to the incorrect idea that once you transition all of your mental health issues will just go away.
On the point of the science, I'm not calling you out or anything it actually has been scientifically proven, the correct term is Gender Dysphoria, its a mental health condition caused by an intense psychological pull away from the birth sex. Essentially you are born with the psyche, thoughts, mindset, and reality that you are in fact the wrong gender. Up until my HRT i've dealt with pretty severe chronic depression as well as a few other more personal issues. A simple two months after my HRT im in the best mental health state I've been in my entire life.
Thank you again for posting your opinion respectfully and i hope we can both learn something from another perspective c:
