Bristol Palin was having fun, doing some work on her reality TV show riding a mechanical bull.  When a heckler started using fowl language about her mother, Palin confronted him.  You can see from the video that she was respectful during the entire time, yet his main complaint with her mother appeared to be that she was alive.

Such is the way of the left.  They are the ones that wish death and pain upon their opponents and when it comes to discussing the issues, have only vitriol to give.  The man stated he was 47.  That is 47 years wasted since he apparently has yet to learn anything.
