Judge Neil Gorsuch
"An employer who fires an individual for being homosexual or transgender fires that person for traits or actions it would not have questioned in members of a different sex," he wrote. "The limits of the drafters' imagination supply no reason to ignore the law's demands."
I know we are talking about employment here but. How often is it that a man doing a female thing with children is put under suspicion or arrested. While a female behaving the same with children isn't even considered suspicious.
The law may not be sexist but its application often is.
