Ultimately transgender people exist, and no amount of legislation that makes life harder for them is going to stop them from existing. Transgender people make a very small fraction of the human population though, so it's likely if you are to implement a policy that allows trans people to use the bathroom of the gender they identify with, it's not going to make much difference. It just means that once in a blue moon a trans woman may enter the women's restroom, urinate, wash her hands, then leave. It's really not asking an awful lot of society at all to allow trans people to use the bathroom of the gender they identify with. If society are unwilling to make this compromise, then the only alternative is we get rid of gender segregated bathrooms. Trans people need to be accommodated somehow. Just because they are a minority doesn't mean they don't deserve rights, especially when their rights are to the detriment of no other person's right,.. and no cis women feeling "uncomfortable" with trans women using the same bathroom as them is not the same as women having their rights infringed on. Quite frankly nobody has the right to feel comfortable or safe in the public sector.. and they have no particular reason to feel uncomfortable or unsafe around trans women. The only reason they do is because of the rights fear mongering and demonizing of trans people.
