This issue is ultimately about legally creating a third gender or class of human beings. Males, Females and Transgender-gay. Federal signs concretizing this law for bathrooms have already been created. The man, the woman (skirt) and the transgender half-skirt. This illusion has been achieved by making gender synonymous with race. Gay equals black-brown or the minority of your choice-they are the same legal identity-victims of oppression. Gays/transgender are now allegedly a race of people. Therefore as a legal recognized race of people they are liberally entitled to special privileges and Laws protecting them-special financing-affirmative action-job preference and so on. I personally do not believe sex or sexual identity should be elevated to the level of race. I have no issues with anyone's sexual proclivities, identities or desires. The same laws protect all of us. I prefer that we are all Americans and not hyphenated-Americans. 
There is nothing exceptional about sexual identity.
