>How does the permission of a Sikh school kid to wear a knife at school infringe on your rights in any way? There's some possibility that he may do harm with it, but then that applies to just about anything anywhere at any time. Cars, baseball bats, plastic bags, a cup of hot coffee, a string or rope, paper, shoes etc could all be used to harm others.

But, none of the above (except maybe a car or BB bat) enter the body, cut vital organs and kill you. Besides, you can't take a car into the school building, and bb bats are there already. So kind of a spurious argument. I can't be sure now if you're pro or anti the carrying of the daggers.
