It's not "marry any man who'll have you" -- it's "please try not to set unrealistic criteria about what a guy has to be before you'll even speak to him". Which is how so many never-married middle-aged women got to be that way.
People post pics of supermodels here, but most guys have some grounding in reality as far as their actual prospects with supermodels (unless you're very wealthy or are a hot movie star yourself)
Define "unrealistic criteria." I'm not challenging you, I'm truly curious.
