The bottom-line problem is that, even if there may be no real danger from the "true trannies", there's no way to know if they are what they say they are.
By allowing this, any man could dress like a woman, claim to identify as a woman, and stroll into the women's bathroom. Even if I were willing to stipulate that there may be no danger from a "tranny", that doesn't hold true for the counterfeits ...
I have to agree with your assessment.
This has been going on for years...unbeknownst to any one.
