Is it just me or does the solution, at the end, suggest that we should encourage young girls not to feel bad? and that is what will solve the problem?
What these modern geniuses fail to comprehend is basic biology. In nature, Women have limited capacity to bear children and therefore wish to select the best mate for their child. Men, in nature, wish to propagate themselves and can do so on a pretty unlimited basis (i.e. Wilt Chamberlain). They want to fight biology with a modern social project -- good luck with that.
In contrast, the project to have men be faithful and give up propagating for commitment has been going on for thousands of years and men have been generally unable to convince women to change the rules until women themselves changed the rules in 1970. How did that work out?
