Women who are below a man's standard's be it fat women, ugly, etc. still have a good purpose. For men who are in a dating/sex slump or for men who are still working on their self confidence, these kinds of women are perfect. For the man in the slump if he goes and rails a woman that is below his standards that will often break his slump. For men still working on their self confidence the act of dating, fvcking, and general interacting with these women can help him build it. As has already been said, you don't have to marry them. Go out, have some fun, and use them to get out of the slump. If she passes the hard duck test and your duck wants to go play in the mud then let him. If not, still, use her as social skill practice. Nothing at all wrong with this.
