No, of course it wouldn't have been "more okay" if she weren't as cute. That wasn't my point. My point was that no grown man has any business spanking a teenage girl. The girl in the video is very, very cute so I included the cute in my phrasing.
If my high school principal had paddled my behind he'd have ended up flat on his back unconscious courtesy of my father. I can't fathom that any teenager is paddled, much less a teenage girl by a grown man.
