And that is destructive of the underpinnings of Western society.
Several reasons:
1. The main principle of Western liberalism - the liberalism of Spencer, Jefferson, and Hamilton - is that human individuals are to be treated as responsible for their own actions. This has been undercut in two important ways: one, the decision of progressives to baby everybody so they could have control, and two, the decision of punitarians on both sides to use human responsibility as an excuse for harsh punishments: "We hereby declare wearing green pants is illegal on pain of imprisonment. You KNEW the law, so by breaking it you intrinsically consented to being imprisoned. HEY ARE YOU AGAINST RESPONSIBILITY? ARE YOU?"
It's important to notice that progressives - initially - were not sexual liberals of the 1960's type. Progressives were always meaning to establish a system to make behavior normative through the use of the state. 1960's liberals have affected this slightly, but the tendency has not disappeared - which is why, if you recall, I mock the sex-positive community for thinking liberals are their friends. They are not.
2. The school environment does shape individuals' thoughts, minds, etc. Not to an extent to which some would argue - there is still free will and you can still sometimes come out from the most Communist environment and become a libertarian. However it's difficult to create a large amount of freedom-loving, self-reliant individuals in an environment that's anti-individualistic.
So you have the modern school - with its cameras, surveillance, suspensions-over-offensive drawings. You think that's going to create self-reliant, free individuals? No, it won't.
3. We have the problem that individuals start wanting to have sex, seek out dangerous stuff, drink beer and take drugs at a far earlier age than we trust them to be responsible for this or equip them to be responsible for this. This is because it is a near-biological inclination in many people. Worse yet, we downright expect idiotic behavior. People live down to this estimate.
