I kind of agree with Allie Jayne because I had no idea what any of this meant at first. So one of my first questions was "How did this happen to me?".
Later, in discussing this with my parents (Trump cultists), they thought it had to do with the way I was raised. And what parent wouldn't feel guilty if possibly something they did messed up their kid?
By understanding the genetic/hormone development that leads to a possibility of being transgender, I was able to assure them that it had nothing to do with them. That made them less defensive and more willing to try to understand and be supportive because it was no one's fault! It helped that my brother is an MD and he confirmed that what I told them is science, not "ideology".
