"Bathrooms don't have cameras and I don't know who'd film an attack."
I do. The perpetrator. Proud of himself for "owning the terfs" – even if the people he was terrorising might have been allies or fellow-travellers for all he knew, or even (if they are so realistic you can't tell they are men) other transwomen.
Gender conforming men who are disabled or small or young get assaulted by other men. That's why I asked "more likely than whom?" This of course is an impossible statistic to gather, given the fact that cross-dressing men who have purported to be female have been getting away with staying clear of the men's facilities by colonising the women's ones, so they haven't been in the gents to be assaulted anyway.
I'd say it's likely that disabled or small or young men have been a great deal more likely to be assaulted in the Gents than faux-women, of recent years.
