it seems that the people complaining are saying that I am creating a hostile work environment just by my presence
In Illinois the law categorizes gender identity under sexual orientation, which doesn't give me the warm fuzzies but
does protect employment.
As for your letter,
The situation is exactly like Whites in the 60s using the shiny new Civil Rights Act to claim that the presence of "those people" itself is a hostile work environment. Point this out, but don't guess who's responsible for the complaint - it just sounds catty and doesn't help your case. Assert that you just want to pee, you feel you have a right to that, and if there's anything else specifically you're doing that's making women uncomfortable, you want to know so you can correct yourself.
Close with the argument that using HR's authority to "intimidate" you into either concealing your gender identity or leaving your job may be a "hostile work environment".* Encourage HR to consult with Legal.
*(Legally speaking, a claim of a hostile work environment must prove that the employer's authority created or at least permitted the hostility. HR might know that. Legal
certainly will. But either way, it's better for HR to be told what to do by Legal.)
