I could just SMELL the Roosh V. bull shit coming out of this thread.
While a lot of bitter, jaded people (men and women) who have been in failed relationships believe that every member of the opposite sex is the same, it's often due to a skewed perception in which they project their insecurities onto others. You get what you put out, and if after one bad relationship you put out broken, damaged, and withdrawn, that's exactly what you're going to get with your next partner. A lot of it is extremely subtle and these guys may not notice what they're doing, but it doesn't mean that all women are abusive, unfaithful gold diggers. That just happens to be the woman they attract when they choose to think that way. Case in point, couples generally begin to treat each other better when they quit viewing one another as gold diggers, cheaters, liars, and commitment-phobes.
The only reason why the dating pool is suffering in parts of the U.S (if it really is at all) is because more and more men are buying into the red pill shit and adopting a false sense of hyper masculinity. When men are praising virgins whilst condemning women who won't sleep with them, or looking for women who want to marry while simultaneously avoiding commitment, what in the fuck are they expecting to attract? These guys want to blame it on lesbians, feminists, and women with mental illness, but in reality they have no idea what they want and lump women into a category of "they're all the same" because THEY are the ones ruining all of their relationships.
