I fail to see what is so wrong with the advice given. My wife has a good friend (a childhood neighbor, a woman) who's having trouble finding a man to be with and the advice given by my mother-in-law and her mother was to move to a place with more men than women. Various suggestions included Alaska, the Oil Fields of ND (she's a teacher, which I hear are in demand in these places), etc.
It seems to me that for some reason, any dating advice that might benefit men is automatically assumed to be misogynistic. Is this advice any different than telling a man to go somewhere with lots of women of the kind he'd want to marry? What's so wrong with it.
