It's not the strangers/drag queens/LGBTQ people that you, or especially kids, need to worry about. It's the men in the family. After working 11 years at a crime lab doing DNA, I don't know if I've come across a kid rape kit with a trans person as the suspect. But there are thousands of them from the dad/stepdad/moms bf/step brother/grandpa/etc. If you want to protect kids, start there.
