>I am countering your argument that this law is useful because it prevents arguments in schools. This is both incorrect and lazy.
Right, because there aren't any precedents with, say, banning smoking in schools. If you leave it entirely at the school level then a small number of motivated parents can harass the schools to get what they want. They did it with smoking[1] ("we don't want our children to leave the school grounds to smoke") and they did it with phones ("we want to be able to reach our children at any time"). Being able to stay "that's the law and that's it" is definitely a good way to avoid having this debate every year in September.
