Not my mother.
To be sure, even if the selection effect I mention is non-negligible, it evidently isn't strong enough to drive pick-up knowledge to fixation.
Mom came up with, "Ask out the fat and ugly girls. They don't have boyfriends."
Needless to say, this "advice" astonished me, and in a bad way. You don't normally expect your mother to express open contempt towards you.
I suspect I'm missing something but I don't discern that in what you quoted (although it does sound simplistic & exaggerated).
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
