The women of our species do the choosing, men react.
Its really simple
If women choose to screw around with players & thugs and ignore nice respectable men, men are going to be players & thugs.
If women choose to not screw around with players & thugs and go for nice respectable men, men are going to be nice & respectable.
Unfortunately nice & respectable has been corrupted into meaning boring and wimpish by too many women...until they hit their 30s and all of a sudden the thugs and bad boys dont want to buy them drinks anymore or just see them as an easy take-to-bed.
Then they want those guys to think they are moral and wholesome.
