When you have strict censorship of the internet, young students cannot receive a full education. Their view of the world is imbalanced. There can be no true discussion of the issues.
Stupidity can win for a moment, but it can never really succeed because the nature of humans is to seek freedom. Rulers can delay that freedom, but they cannot stop it.
I think by not letting young people be fully informed, how can they have energy and passion and the right picture of the world? I think that's the true crime.
