Because it occasionally needs reinforcing by us cis women, I'll say it again.

Trans women are no threat to me, my femininity, my gender, my sex, or my rights.

They are no threat to the kids I know. They are no threat to you (unless you are a Nazi, because just because one is a woman, doesn't mean she can't throw a decent punch).

They are not threatening on a train.
They are not threatening in the rain.
They are not threatening to the kids.
I wouldn't hate 'em, not for quids.
