|From PBS' Growing Up Trans|
It is pointless to continue to write about each individual anti-LGBT group that has an issue with transgender people. They are all insisting that allowing Caitlyn to pee in the women's rest room is going to permit men to pretend to be transgender in order to gain access in order to do something to women and children. Many of them probably believe that is the case. However, in the real world that just doesn't happen and the same criminal penalties apply with, or without, transgender accommodations.
This is mostly about children. Christians are going to have to accept the fact that transgender and gender nonconforming kids do exist. Allowing them to use the rest room consistent with their gender identity doesn't threaten anyone. Nor does it abridge privacy.
The most informative source on trans kids might be the PBS/Frontline documentary; Growing Up Trans. It is viewable online and via Roku, Chrome, whatever. Both sides (I hate to admit that there are sides when it comes to kids) would benefit from watching this one hour 24 minute video.
