how can we have a good faith argument when you simply reject the validity of the science and research on this issue?
I don't know how to hammer this into your head, but it is not "a decision". No kid wakes up and "decides" to be trans. just like no one wakes up and decides, 'well golly gee, I'm gonna be gay on this beautiful Wednesday'. human sexuality is not a conscious decision. that's why praying the gay away doesn't fucking work!
you have simply decided that you know better than scientists (because your religious leaders said so?).
where in your holy book does it say you should hate trans people? and/or gay people. feel like we need to get to the very root of this allegedly religiously-proscribed bigotry to fully understand it (and hopefully, help you overcome it!)
