The state of morality on the American college campus seems to be in perpetual decline, and I have shuddered to think about what it will be like in a dozen years when my own daughters will be getting ready for college. But from a liberal college in a liberal state comes a small ray of hope. Tufts University has revised its guest policy for dorm visitors for the new school year to include the following new rule: You may not engage in sexual activity while your roommate is present in the room.

Shouldnt this be obvious? Word from my friends with kids in college is that, shockingly, its not. Nor is it a problem unique to Tufts.

So a tip of the hat to the Tufts administration for having the courage to draw a line. And if Tufts can do it, any school can.
