"but why couldn't you have stayed a boy if you still like girls?"

I don't know, why do you wear glasses if you can still see blurry color splotches?

I can't wait for my parents to get shittily religious about transitioning, I absolutely know they'll try to say some bullshit about god not making mistakes and I'm just going to start listing all the things they've modified about themselves over the years and tell them to get rid of/undo all those things first because "god doesn't make mistakes" and only those who are without sin may cast the first stone.

Personally my all-time favorite person who identified as Christian was actually asked to leave my parents church because he was outspoken about accepting lgbtq people because the Bible in its older translations don't talk about LGBTq people at all, and trans people "just had some extra trials given to them to overcome, and we should celebrate them doing so, not tell them to go back to what they were pretending to be before" and honestly that guy was based AF for saying something like that 20 years ago in Ohio of all places. It's not Mississippi, but it's called the Bible belt for a reason.
