Conservatives usually counter that there are examples of men sneaking into women’s bathrooms to attack women. But as
PolitiFact reported, none of the examples cited in the US happened after a city or state passed a nondiscrimination law or otherwise let trans people use the bathroom or locker room for their gender identity. Instead, these seem to be examples of men doing awful things regardless of the law — which has, unfortunately, happened since the beginning of civilization.
One example is a case in Toronto, Canada, which now has a nondiscrimination law, in which a man disguised himself as a woman and attacked women in shelters. But the attacks
happened months before Ontario (Toronto’s province) protected trans people in a nondiscrimination law. So the law couldn’t have been the cause.
