Hypocrite of the Week!

Hypocrite of the Week! Bristol Palin starring in an anti-teen pregnancy PSA advocating abstinence as a preventative measure — something Bristol not only knows in her heart of hearts is not effective, but is a living, breathing proof of that fact.

...or am I wrong and it's a logical fallacy?

Since she didn't TRY abstinence, then she's a warning sign to other kids to try it? Now I'm confused. Feel free to chime in.
