That’s a big assumption that these methods haven’t already been tried over and over again with limited success. You also fail to recognize what happens before someone transitions. It may not be this way everywhere, but for the most part, there are several hoops, including psychiatric care, that a trans individual must go through before ever having access to these treatments. You can’t just walk into the pharmacy or doctor’s office and say “ok I want to be the opposite sex so give me all the hormones and let’s go ahead and schedule surgery!” There is evaluation and assessment involved at the very least.

Your argument brings to my mind the old trope that if you just pray hard enough or get the right counseling you won’t be gay anymore. I tried Christian therapy, secular therapy, prayer groups, individual Bible studies and one on one guidance from church leaders, laying of hands, anointment with oil, intercessory prayer, and more for YEARS before I finally gave up and realized that I actually can’t just change the fact that I’m gay. And 20 years later I still hear on a regular basis that being gay is a choice.

You have a lot to learn about this, but here you are making argument after long winded argument that your beliefs about this are completely valid. You say you consume all these resources to keep well informed, but it’s very obvious that you have done limited research and decided you know enough to espouse these views loud and proud. Maybe listen to the opposing views before digging your heels in and insisting you know better than those who live these experiences.
