In what way could I be accepting/supportive of transgender people?
I acknowledge that people with gender dysphoria exist, and I have sympathy for them. But I don't personally believe that sexual reassignment surgery (SRS) is the proper solution for their condition.
Maybe science doesn't agree with me on this, but to me, there's just something wrong with pretending to be something you're not, just because you feel like you should be something else. I feel that it would be much healthier to learn to accept who you are; to come to terms with how you were born. I have no idea how difficult that is for someone with gender dysphoria, but from my point of view, that'd be a much better treatment for people suffering from gender dysphoria. To accept who they actually are instead of pretending to be something they're not.
I would guess that in the near future, people will look back on SRS as a barbaric solution to gender dysphoria.
