What about when you're a dad, taking your young son into a public restroom, and have to place yourself between the urinals because of the creepy dude who's come in and used the very next urinal and is trying to get a look? All men, all in the men's room.
How about the men and women who go into restrooms at retail stores and smear their shit all over everything? (This happens way more often than you might think.)
And I got news for you weirdos: if you think that a gender sign on the door is going to stop anyone whose aim it is to go into a public restroom for sexual jollies, you're fucking wrong.
None of that has anything to do with transgender people.
