a trans girl friend send it to me and we were mutually of the exact same two thoughts
1 - this did not happen, this is "after I came back from vietnam" level shit
2 - if it DID happen, Rowling's social skills are so eroded she genuinely thinks she made a point being weird and uncomfortable
1 - guy was freaked out when Rowling started spouting TERF bullshit? That sounds entirely probable to me.
That she failed to properly identify the source of his discomfort? Also likely.
That's she's terrible at reading people? I'm not surprised.
