What a load or rubbish. This is clearly just another move by autocratic school administrators to allow the administrators to discriminate and punish certain students. It's a lot like the "no gang uniforms" rules 10 or 15 years ago. If you read those in isolation, you'd say, "Wow, they're going to ban the Letter Club and the cheerleaders?" But of course, the rules are very selectively applied, and DON'T APPLY to children of wealthy parents, conformists and suck-ups. Rules against certain kinds of clothing only get applied to people who for whatever reason, fall outside the Circle of Insiders.
