Not according to the law in many places, not according to her gender, and not according to any reasonable consideration of the evidence. Is this a woman?
Why? Because he was born with a vagina? Why should that trump
every other factor here? Particularly when it comes to the question of which bathroom he should use?
And women have the right to expect that men won't be allowed in the women's bathroom even if they put on a dress and a wig.
What pressing concern do women have here, exactly? Fear of sexual assault? Oh, right, please, cite the cases you know of where a transwoman committed sexual assault in a women's bathroom - I can tell you right now there
aren't any. Privacy? Most transwomen just want to go in, do their business, and get out like anyone else. They have even more interest in respecting other people's privacy and having their own privacy respected, because trans people face
incredible amounts of violence for their use of public restrooms, regardless of whether they use the restroom that corresponds with their sex or the one that corresponds with their gender.
Meanwhile, you know what's stacked up against that? General mental health - WPATH, the APA, and the AMA all recognize that living life as a member of the opposite sex is, in fact, part of treatment. Physical safety and wellbeing - trans people forced to use the opposite gender's restroom face far more harassment, assault, and abuse, and if you look at Shawn Stinson up there, you can probably figure out why. The gender of the individual - transwomen have a
female gender. I realize you don't accept that gender is a thing which is distinct from sex, but you're just wrong - you might as well deny that genes exist, or deny that testosterone is a thing people have.
Our anatomy defines our gender.
You're right! Our anatomy also defines our sex. These are two distinct things! For some people, they get a female gender and a male sex. They may be the rare exception, but that does not diminish their existence, or their rights.
But who cares about the 20 other "normal" 16 year old girls in the locker room?
They're there to shower and change, not show off each other's genitals. If they have a problem with this transwoman, then yes, that is
their problem. They can get over themselves. You might as well complain about a gay person sharing the shower - and they're more likely to stare.
I
guarantee you that there are more cases of a transwoman being murdered for entering the men's bathroom than of transwomen raping women in the women's bathroom.
