I recall when the TV character Murphy Brown, decided to give birth as a single parent to her ex-husband's and her child, VP Dan Quayle pushed his way in uninvited and said that she was setting a bad example by becoming a TV character single mom. Now, it appears that single mommery is all the rage, and young Bristol Palin is some sort of heroine for getting herself knocked up.
