So, basically what you're saying is that women, (particularly, although I also know some teenage boys) who prefer privacy while peeing are somehow mentally ill and must be ripped out of their insanity by a six-foot male in 4-inch heels goggling them over the top of a public restroom stall. (And, yes, I have had that experience and know other women who have had it also). These fearful and unfair people who think their body shouldn't be under public display of the opposite sex will  get used to being goggled and their daughters won't even think it's unusual and the whole world will be better off for them getting used to being sexually harassed. And, hey, the occasional sexual molestation of children ... that will only grow the number of transgendered, so it will meet your goal and that means there's nothing to worry about.
