Whether you have children or not, you've probably heard of Hannah Montana (or perhaps Miley Cyrus); Selena Gomez from Disney's "Wizards of Waverly Place"; or the Jonas Brothers, the boy band that elicits ear-splitting screams from their female teeny-bopper fans.They're big names in the entertainment industry, even though the oldest of the bunch is only 23.

What you may not know, however, is that each of them has taken a pledge of purity. That's not something you normally hear from the morally bankrupt land of Hollywood where anything goes ... and usually does.

Of course that doesn't mean these purity-ring-wearing Disney stars haven't been hit with criticism about their own "morals," especially Miley Cyrus and her provocative picture in Vanity Fair. On the other hand, at least the notion of abstinence has crossed their minds and, to varying degrees, their lips. And that may, perhaps, positively influence their young fans (even if it's tossed to the wayside in their own lives). Not everyone thinks that's cheer-worthy, though.

Jessica Valenti, founder of the vaguely pornographic sounding Feministing.com, has decided that there is no such thing as virginity in America's young girls and the Today Show is entirely pleased with itself to give her a national TV venue from which to say so. Never mind how silly it all sounds.

On April 23 Valenti and Today pushed the idea that sexually active girls should not be thought of as a problem, that an expectation of virginity is harmful, and that religion is a baneful influence on young women today. Valenti says that if young men can have their sexual exploits given a wink and a nod, then so should the sexual activity of young girls.

Naturally, being a good left-wing, feminist, Valenti draws all the wrong conclusions and advocates all the worst solutions to address the real problems in American society. Just as naturally, NBC gives a legitimate stage for her absurd proclamations and ill-thought-out prescriptions.
