Express your disagreement with the idea of having a transgender person using the same locker rooms.
The Lesbian commenting above is a perfect example.  They care only about themselves - no need to read the US Constitution nor accept that many of us are sickened by their actions.  A man showering in the same locker room at a pool where women and girls go to the bath room and shower??   Sick.  Call the police - there's a pervert who needs to be arrested.  Claiming that he is a she makes him a mentally ill pervert.
