What we really need to do is teach actual politics to children.

Kids should be wiping the floors with these neo-liberal professors. Instead, the children are filled with order-following indoctrination that we need a strong leader. And so, you have to vote for that strong leader.

But really, all of these ages are meaningless. All of the arguments come down to, ulterior motives. We want cannon fodder before they become wise enough to say no, we are not charging those cannons. We want kids to drive so we don't have to drive them. We want kids not to vote, because they will vote differently then we want them to.
