Well, first of all I disagree that her defense of trans women is disingenuous. Her points are well thought out. She points to specific situations where trans women are vulnerable. Just because she has another concern doesn't invalidate her concern for trans women being vulnerable.

So her heinous viewpoint is she has concern for girls in restrooms and locker rooms? Why is she not allowed to have this concern? The rest of the country/world is not San Francisco. Where I live I've never seen anything other than Men and Women restrooms. Sure adding a gender neutral bathroom could help with the issue but they don't exist in the vast majority of locations in the US. I have two high school daughters - one with autism. I'm sorry if its a dangerous trope from half a century ago - but my wife and I would be concerned with a trans woman sharing the locker room with them. Certainly my non-autistic daughter would feel uncomfortable. My daughter with autism wouldn't care because she has trouble with boundaries and being appropriate which makes it more concerning.

So now you'll say I don't care about the fate of trans people. Nope. It's possible to have concern for them and concern for non-trans people.
