To center on one group, transgenders, as being the only ones of those who would conceal their appearance too prey on people, as being the majority of those types of predators, is setting yourself and those you love up for a bad surprise - you've made a mistake, there, Blondie. The same mistake people on FB made about me.
I don't think transgender people are any more likely to be sex offenders than cisgender people.
My concern is that rapists, sex offenders - cis or trans, doesn't matter - might take advantage of a situation that allows trans-women (biological males) into the ladies' restrooms.
As it stands, as long as a person born male says he's a woman, he can use the ladies' restroom. Such a person doesn't even need to have an operation to remove the offending penis and testes. He can be a pre-op trans-woman.
Now, that's what I'm concerned about. An opportunist rapist who's really cis could claim to be a pre-op trans-woman.
Women who share these kinda concerns mustn't be dismissed as irrational. They're being perfectly rational, actually.
Do you get where I'm coming from now?
