There are too many people that don't want anyone to have our God-given/Constitutionally-recognized (however you choose to see them) rights, period. They view rights like free speech as dangerous because such a right allows others to criticize them and possibly undermine their authority or whatever else it is they're afraid of. Since it's easier to condition young people to not claim those rights than it is to strip those rights from older people , who are already accustomed to exercising them, that's the route that has been taken.
That's why schools now have essentially the same authority over students that the parents do. In many ways, it's nothing more than an end-around that bypasses the First Amendment--and many others. Schools were transformed from a pure agent of the state into quasi-parental figures without losing their state-given powers of coercion.
Since there's no magical age at which people begin to think responsibly, schools have decided that allowing no differing thoughts of any kind is the way to go. And they can, because they have that power. Eventually, all of society will be like our schools; no one will know how life could be different because no one was ever allowed to taste the thrills, or responsibilities, of freedom.
