Mormon Voluntary Modesty Police Force!

So the latest episode of the "Voluntary Modesty Police Force" happened on Tuesday at BYU for those of you who haven't heard about it yet living under a rock .  Like last Fall, I dismissed it just as that one "crazy" guy you get in a singles ward.  However, one of the writers on FMH stated this, "As long as we keep teaching boys they are too weak to behave themselves, they’re going to believe it," and it got me to thinking.  In the LDS (Mormon) Church, young women are taught sometimes that they should dress modestly because otherwise men will have unpure thoughts.  In fact, I read something to that effect in one of the conference talks this past year because I remember disagreeing and stewing over it for several weeks.  I ended up just tossing the idea out the window because I still disagree with it.  I think it's potentially harmful to teach young women that they are "guardians" of men's thoughts and virtue for several reasons-one being that it can give young men the idea that they are powerless over their thoughts.  
The letter above is a Young Man reminding a Young Women of this concept that was taught at church.  Was this just a "crazy" guy at BYU-I and BYU or are we going to see more instances of "skinny jeans" that embarrass most of the rest of us?  What do you think?  Oh, and if you disagree with me--I'm more than happy to hear what you have to say.
