What someone's birth certificate says, or what their genitals look like (both of which can be changed by the way) doesn't really matter here. We don't assign bathrooms based on who has a penis, and who has a vagina.
Except, that's exactly what we did. The ladies' room is for humans who have vaginas and the (assumed) reproductive parts to go with it, and the gentlemens' room is for humans who have penises and the (assumed) reproductive parts to go with that. No one made that decision based on some imagined hate for a 6 year old transgender kid a couple thousand years into the future.
Which still boils down to every other woman is allowed in the women's bathroom except those who someone doesn't like.
Or, those women who have penises\testicles\etc. Again, it's really not about hate. It's about physical anatomy and having some sort of real standards so we aren't opening up exploitation for every Joe who decides to say he's now Jane just so he can get into a girl's bathroom without being questioned. We have a right to be safe too, you know.
No, you're just being a bigot. If you wish to refer to someone's legally recognized gender, then say that. Calling girls "boys" is just hateful.
It's hateful if someone is really going through the process of changing their gender. Then you are just taking a shot at someone who is already going through a super tough time of being put in the wrong body in the first place. But that doesn't mean that we should just sit here and say, "ok, since we don't want to hurt the feelings of the small percentage of real transgendered people by asking them to use the restroom assigned to their current physical
anatomy or a private restroom, men are now allowed to use the ladies' room if they say they are women." I mean, how stupid is that?
So what is the answer? Personally I think the school had the right of it. The 6 year old clearly has some things she is going to need to work out, but while she is doing that - using the nurses' private bathroom is probably the best way to handle it. For the rest of us, I do think that adding a private restroom to public locations, or just converting them all to private restrooms is the best answer. It will be safer for everyone involved. Women don't have to look over their shoulders and wonder if that person really is a transgender or is in there to rape her because no one thought twice about him entering, transgenders don't even have to answer a question - they just do their business, and everyone wins.
