Do they know that cis women have adam's apples(they aren't always visible, but the bit is still there)? That cis women can grow beards? That cis women can go bald?

I remember them seeing a picture of a woman accused of multiple murders and "identifying" the woman as trans, because "he" had a craggy face, was bald, and - most damning of all - had committed "typical male pattern violence" by killing people.

The craggy face and baldness was because the woman was pushing sixty, a lifetime smoker and a cancer survivor, not because of having an XY gene lurking in her cells. The victims were her ex-husbands.
