I'm torn on the Nose Ring Theory
My personal experience, i've never dated a woman with a nose ring or facial piercings, that said they've always been nice to me without acting strange or unusual.
outside of my personal experience, i've noticed that in my area, they don't tend to have long term relationships. Which is less a generalization and more a comment on the society in my small hick town.
idk, seems like a scapegoat with cherry picked examples of problematic people in general.
