bristolpalin getty Bristol Palin, Keith Olbermann's 'Worst Person in the World,' fights back on FacebookBecause it just wouldn’t feel right if we went a day without acknowledging Bristol Palin‘s surprisingly enduring post-“Dancing With the Stars” shelf life, let’s quickly touch base with Alaska’s favorite daughter…

]]>points us to Palin’s Facebook page, where, after being branded Keith Olbermann‘s “Worst Person in the World” du jour on his show earlier in the week, she’s penned a small open letter. Olbermann’s issue with Palin stems from her recent PSA for abstinence and safe sex, which he sees as hypocritical given her former teen pregnancy status. Palin, does not agree. And makes a few good points in her rebuttal to the somewhat bullying remarks. “Mr. Olbermann fails to understand that in order to have credibility as a spokesperson, it sometimes takes a person who has made mistakes,” she writes. “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. Recovered addicts lecture to others about the risks of alcohol and drug abuse. And yes, a teen mother talks about the benefits of preventing teen pregnancy.” Get it, Keith? It’s like “Scared Straight” — only with sex and the Situation.
