Okay, so then if a government behaves as if "Language is Bad", then what programs does it set up, and how does it harm the people? It might be irrational, and it might be anti-intellectual (neither are good), but as campared to euthanasia, bigotry of some sort, A religious rulership, etc. I don't think anti-intellectualism is all that harmful.
It might have some minor effects, but I doubt anyone will be harmed by the government encouraging nonverbal communication. Unless you're going to discribe some bizaare sci-fi horror plotline it seems highly unlikely that any government will shoot you for speaking out loud.
I'm talking about actual harm. Things that take away a man's natural human rights. Life, Liberty, and Persuit of Happiness. The right to be tried in a court instead of being shot in the back in the middle of the night. The right to not be seached arbitrarily. The right to property. Etc. Etc.
You don't have the right to live in an "intellectualist" society, nor the right to have a government change your nappies. You don't have the right to an easy life.
