text: The bottom line here is first that appearances count, and second that Canada, like most Christian-heritage countries, has nudity taboos that are emotional rather than rational. As far as I know, the ability to read minds does not exist; I cannot see into another person's mind to find out what gender they perceive themselves to be, but when they are naked I can see what gender they appear to be. That's the first point.
  
  Second, Canada's most common nudity taboo is the taboo against being seen naked by any adult member of the opposite sex that you are not in an intimate or medical relationship with. The combination of "appearances count" and the nudity taboo means that most women will be distressed at finding themselves naked in the presence of an apparent male, especially if "he" is also naked.
