If students at a high school not too far from here want to attend the Homecoming Dance tonight, they must have signed a pledge which says that they will "face each other" on the dance floor. They must also promise not to engage in any "freak dancing".
Nothing newsworthy about this. Adults have been objecting to teenage dance moves almost since teenagers were invented. While administrators are somewhat justified in their concerns over a few MTV video moves, that’s one reason you have chaperones. However, I don’t think the students have a case when they claim that the rules violate their "First Amendment freedoms of expression". Nor does the parent who goes overboard with the assertion that "authority’s gone mad".
But the t-shirt worn by one student does make a very good point: "How are we supposed to do the hokeypokey if we can’t turn ourselves around?" How indeed!
