Bristol Palin defended herself Thursday against an attack from MSNBC personality Keith Olbermann, who called her "the worst person in the world" because she preaches abstinence to teens even though she was an unwed teenager when she became a mom.

On her Facebook page, the former "Dancing With the Stars" contestant said she won't let Olbermann distort her message about the difficulties of teen pregnancy and that Olbermann is confused about what constitutes hypocrisy.

"In order to have credibility as a spokesperson, it sometimes takes a person who has made mistakes," she wrote. "Parents warn their children about the mistakes they made so they are not repeated. Former gang members travel to schools to educate teenagers about the risks of gang life." About The Author: Steven Rogers
