Not true. Have you ever been in a position where you had to clean public restrooms? I did for an upscale park and several retail stores in my teens. 100% white area. The womens' restrooms were always filthy as fuck. The only time I've ever seen shit and blood painting on the walls were in those, as well as mini liquor bottles in tampon bins. In contrast, the guys piss on the floor; big deal. Restrooms aside, I've had several girlfriends where I would have to ride their ass to keep their rooms or apartments clean, often resorting to doing it myself.
