The far right has lost the battle on gays serving in the military.
They've lost the battle on same-sex marriage. 
So now they are picking on trans-gendered people.

Everytime they lose they "retreat to a new, smaller hill that they say they absolutely must defend if society is to survive. Okay, they say, we can live with gay people not being banned from teaching, but if they can get married, that’ll be a disaster. Then: Okay, we can live with gay people getting married, but what really matters is that bakers be allowed to discriminate."

"Again and again, the massive social disruption that conservatives have predicted when gay people are granted civil rights has failed to materialize."
