Never, in the history of the US, English or any other modern Western Law, beginning with the Magna Carta through the founding, has the "interpretation" of "sex" EVER meant "You are who you think you are". The law is NOT discriminatory, and the 4th Circuit Justices, who based their decision based on an opinion letter from an unelected government bureaucratic entity (DOE), ought to have impeachment proceedings started against them for failing to execute, faithfully, their oath of office and to defend the Constitution of the United States (which I know Progressive Leftists want discard in the name of "A Living Breathing Document" but they cannot define that, separate from the Amendment process), and not accept “opinion” as fact and Constitutional law. The Congress has no guts to do their part to check the judiciary in our system of checks and balances. If we define HB2 as “discriminatory” then we accept “anarchy” and then we descend into the abyss that ancient Greece fell into : Every Man for Himself”, and we know the end thereof.

This is a case where an ACLU leader resigned because grown men walked into a women's bathroom, because they said they were really women (which is total crapp) and scared her daughter beyond belief. At this point, she departed from her organization's stance, and resigned in the name of her daughter’s mental and physical safety. If this is what you mean by "discrimination' then you are, indeed, mislead and chasing every "wind of opinion" or "tossed to and fro with every wave of populous opinion".
