I hesitate to say anything because I am going to offend well meaning people that I disagree with.
Regardless if you are homosexual or heterosexual, I say more power to you; live your life the way you want. If you have had a sex change operation (A.K.A Gender reassignment surgery), because that makes you happy, I say the same thing: More power to you; live your life the way you want.
But if you want to dress as the opposite sex, don't expect me to accept your fantasy. I see well intentioned friends say that nobody is threatened in bathrooms, and for the most part they would be correct. But they assume that 100% of the population is going to behave themselves. The reason why we have a standard that a men's bathroom is for men and a woman's bathroom is for women is to prevent abuse. Taking away a standard makes it easier for a tiny percentage of people to abuse the system.
There have been a couple of incidents where women entered a bathroom that I was using. This is not only a violation of my privacy, but I also find it disturbing and it makes me angry.
