Oh Lord...How many times will that question get asked...it's probably the first question asked when man developed speech...i still haven't heard a definitive answer to it. Men just don't get it....BTW, we know why men hook up with trashy women.
There was a time in America that a number of women chose dishonorable men to hang out with but not in the percentages that there is today. At that time, only the girls that suffered really low self-esteem seemed to think that they deserved scum but that seems to be the norm today rather than the exception.
Parents (or even single moms) taught their sons to be gentlemen of honor. Today's moms seem to raise boys who will never grow up and low lifes.
