You don't seem to appreciate that gender identity, gender expression, and sexual orientation are three completely separate items. You also don't seem to appreciate any of the available statistics that demonstrate gender identity, gender expression, and sexual orientation do not give a person a high propensity to go out and rape; actually those three loci much better describe a victim of one type or another - verbal abuse in school, lack of access to programs that produce academic achievement, discrimination in housing, discrimination in employment, discrimination in access to public services, violence, and more.

You also seem to favor some sort of officially sanctioned penis inspection day (if you don't want your daughter sharing public space with what you referred to as a girl with a dick in your first sentence) to determine who goes where; when the law actually doesn't require bottom surgery to be granted a legal name change and update of gender markers. In Texas courts the judge doesn't actually require trans* Petitioners to disrobe and prove they have had bottom surgery (both the orchiectomy and the penectomy) by clear and convincing evidence before they can sign off on the name change.

Have you ever actually met a trans* woman? If they have not had complete bottom surgery they are often extremely self-conscious of the genital items they have that are opposite gendered. They do not parade up and down the lady's locker room naked pointing at it wildly and shouting "hey sisters, check out this feminine dick!" If you would put trans* women (sans penectomy) in the men's locker room then you are enforcing the absurdity of penis inspection day - some sheriff or other constabulary at the entrance to every public restroom acting in an official capacity to check what's what downstairs.

If you wouldn't cater to the most vulnerable members of a community with a simple kindness that carries with it zero externalities I could only wonder historically what side you would have been on in other eras like the Holocaust, the American Civil War, and the smallpox blankets to the Native Americans.

You also seemed to miss the point of the article that rapey/sexual assault (including exposing yourself for a giggle) activity, whether it is in a bathroom, locker room, or in the hummus aisle over in the Whole Foods, is regulated by the Texas Penal Code and is prosecuted by the District Attorney's Office. Being trans* does not cloak you from a criminal prosecution if you commit a crime; doing crime in a lady's locker room is not some super odd loophole in the state or federal criminal jurisprudence either. Crime carries it with repercussions, and regular people understand that as part of the social contract.

Sanity is needed principally on only one side in the public "debate" - the side that thinks trans* people are not people.
