However, if this sad occurrence came to pass, even stupid women would WISE UP and stop sleeping around.
When abortions were rare and shameful, and birth control wasn't easy to find, women did not "put out" that much, and men knew that they would be socially forced to marry a woman he impregnated. That is the way it should be.
Yaelle, it's the larger society (and that includes you and me) that no longer stigmatizes men for failing to do the "honorable thing."
