I have a ten-year-old son who plays hockey. He was raised in the post-lockout era of rule changes. When he sees a mild hook, of the kind that would have passed under the radar ten years ago, and a penalty isn't called, he is outraged to the point of turning blue in the face. When he gets out on the ice, the idea that he can use the stick as a way of stopping another player is something that doesn't even occur to him.
I hope the analogy is clear.
