1. I grew up Conservative Christian
2. At 21, I came out as gay
3. At 30, I'm coming out as trans
I have no idea what most people from my early days think. I do know there is essentially no sex ed there (did I mention I also spent all 12 years of school in the same building as the church, and it was run by the pastor's wife?) Despite the vast availability of education online, the nature of online allows anyone to focus on what they want, and throw out the rest. Heck, the ratio of pregnant girls in my school probably wasn't much different than a larger public school.
It sucks that each generation seems so progressive in pockets, with blatant ignorance being too much the norm. That ignorance didn't start with the current generation of teens/20-somethings, it's been passed down. I have cis female friends that are running into similar issues of having to explain sexuality or equality or the ridiculous "would you ever questions." Talk about being sick of explaining things
