So the only place that could potentially be safe in my town is the library. They have been very clear from an overall policy level that everyone is accepted. However, there is one librarian that I am 100% certain is homophobic and transphobic. Since I work there as well, I know some important policy rules that give me an unusual opportunity. You will be fired immediately and have card privileges permanently revoked (closest they can legally do from banning someone) if you discuss what a specific person was looking at or discuss information related to a patron's checkouts with non-employees. If I were to check out a bunch of books on lgbt topics and heavily imply that I am trans without directly saying it, she will absolutely tell my parents. I will then have proof, through them asking me, that she revealed my private information. This would ruin my life, but make it safer for other people because she would be gone.
In case anyone is wondering how I know she will tell my parents, my mom is friends with her. I've had a ton of secrets about what I do while I work leaked through her.
