Not insane. But I think this gets ingrained in children at young age and they just follow what their parents do in the same way that if you put a golf club in a kids hand and said this is the greatest thing ever their entire life odds are they’re going to believe that GOLF is the greatest thing ever, and they will devote their life to it.
I see it all the time during Bible camp. Parents throw their kids into it and then they rant and rave about how what a great time they had, and how they believe and all this nonsense. Well, of course they do. You didn’t expose them to anything other than what you are already thought.
