Some decent men are being rejected because they aren't "exciting" enough. I guess nothing compares to the "excitement" of a bad boy coming home drunk or stoned and ready to kill someone. Popular culture celebrates the violent bad boy on one hand and the wimp (as if to make up for the excesses of be bad boys) on the other. Boys of one sort or the other are wanted, but not men. Some foolish women have bought into this. One can never underestimate the power of stupidity.
Actually, woman crave status and power. "Bad boys" exude a certain power or potential future power (likely to become leaders.) Attraction to the "bad boy" is like an early investment on the ground floor. She's hoping he'll take her to the top with him.
It has been found that women also prefer to have sex with the "bad boy" type, but will often prefer the more "good guy" type for helping bring up the baby.
