The fact that you refer to trans women as "males" will more likely cause people to accuse you of transphobia.

Yeah, so? I've been called worse; and I can take it. It's you I was talking about. I thought appearing transphobic is something you'd want to avoid at all costs, and being accused of transphobia is something you might be concerned about.

Tellingly, you didn't address any of my points. Instead, you immediately brought up Keira Bell and tried to make it seem like the issue you raised is whether

someone like her in appearance and voice could be mistaken for a trans woman.

Which is ridiculous. Look at Bell's face, hands, feet, body shape, bone structure and the way Bell moves and walks.

Keira Bell is also totally beside the point in this particular convo, which you started. Because you specifically asked

GC: How would you react if you saw a trans woman in the women's restroom?

Or someone who appears to be a trans woman?

Now you say:

I think its obvious I'm referring to trans women who don't pass.

But I thought passing didn't matter? That trans people don't owe it to the world to do anything to change their appearance to try to pass as the opposite sex. Because everyone is just supposed to believe that trans people are whatever sex they say they are.

Also, since you brought up "passing": who decides who "passes"? Most males who identify as trans think and insist that they pass, but many female people like me disagree. Whose perception do you think should win out here?

The central point remains: the questions you raised are a tacit admission that you believe women (who are GC) can always, usually or frequently tell when males are in women's restrooms, no matter how those males identify or present. This goes against the fundamental part of the QT creed which says that none of us can ever tell because it's impossible for anyone to figure out if adult and post-pubescent males are actually male without "looking in their pants" and doing DNA tests.
