Yesterday a commenter tried to lay the creation of transgender identity at the feet of "a loving mommy" who encourages a little boy to play with make-up, nail polish, and cross-dressing while "disparaging male boding activities with a daddy she resents."

This ticked me way the Hell off. Not only does it completely ignore the existence of trans males, it has absolutely no scientific foundation.

Doctors at Boston Children's Hospital combed through their patient records and discovered that 8.2% of the young people treated at the clinic between 2007 and 2015 were being raised by adoptive families. This compares to a rate for the general public of 2.3%.
