The concerns I was talking about are not safety concerns. I know the statistics, and I'm not arguing them.
The concerns I'm talking about have to do with the motivations of men using the ladies room, and whether they're getting some kind of pleasure out of the experience. Even in many (though certainly not all) of the more "normal" cases here, there are undertones to what they do and why. In just as many or more cases, there are pretty overt sexual motivations and/or feelings from the experience. That's not even getting into the caricature image of women so often discussed/pursued here and the uncomfortable feelings that come from that.
I cannot in good conscience tell women that men in dresses have only pure intentions and a need to pee. There's more to it than that in far too many cases. That is what I see evidence of every day, much of it here.
Men in dresses may be "safe" statistically speaking, but that's only part of the concern. Nobody wants to be an unwilling participant in someone else's kink.
