The state does not have the power to override nature. We can sputter and posture all day, but if you are born male, you are male, even if you want to pretend otherwise. Cosmetic surgery, artificial hormones, and drivers licenses do not transcend biology.
If she was able to provide identification to state she was a female, the spa has to accept her. Biology doesn't matter, she had the documents (in this case, her license) to show she was a legal female.
So you can declare yourself a dog and start shitting outside without repercussions?? About the same thing... You don't just get to state what you BELIEVE you are in spite of biology
