How can you guys support this?

I'll have to disagree with BarkingFish here.

Considering That Florida is in the US, that this applies to public schools, and that our Constitution applies in public schools, I'll have to ask for proof that this sort of clothing and fashion statement is a legitimate distraction before I could agree with this widespread ban. After all, youth are citizens, too.

And if we can ban whatever we don't like, then the First Amendment doesn't exist, and neither would the Constitution. I hope someone challenges this in court.
