- they can already vote, they can already marry, they can already serve in the military, they can already enjoy full citizenship in every way shape or form, the only legislative question left is "where to pee."

In some ways its true but some interesting questions come up when you legislate gender and race into law and then accept that race and gender are fluid. If a company/government/university has a quota for men or women then can one change their gender to qualify. There are grants and carve-outs for woman owned businesses for example. Can I self identify as a black woman can claim them? This wouldn't be a problem if we just didn't put gender and race into law but since we do, it is.

Its the same argument I had against gay marriage expansion, its not that gays shouldn't marry its that they government should have no say in what is/isn't marriage. Marriage licenses and marriage as a legal state recognized concept should not exists. One should not get any benefits or have to pay extra taxes just because they got married.
