Doc, you're being a bit of an arrogant asshole through this. The first section you listed is just misconceptions and things like that - I barely know shit about space travel, but you know what? I have no intention of going into space so why would I need that knowledge? Same for the rest of the topics in that section. If you have no interest in a topic, there is literally no god damn point in learning about it except for situations where someone would look down on you arbitrarily for not knowing a god damn thing about a topic with virtually no interest to you.
Second section: I'm in eastern Tennessee, and you know what? All of those were taught in my school system. What a shock! If the students are idiots, they're idiots. You can't teach someone if they don't want to learn. Ranting about this is pointless. I know I sure as hell would just tune out someone lecturing me about something I flat out don't give a shit about.
Wilderness: Okay, almost no one is going to be out in the wilds unless they want to be there. In which case, they're either soon to be dead and that deals with that problem or they know what they're doing. So once again, utterly pointless. I know I would've fucking slept through any class about wilderness survival. And swimming? I couldn't swim until I was 15. I'm 21 now. No shame in it, cause you know what? Swimming lessons are bloody expensive and there are situations where there's no god damn pool to learn how to swim.
And teaching people how to fight is just fucking idiotic. The world is violent enough and teaching someone how to actually hurt someone instead of flailing at them would just make things worse. If you're going to teach anything, teach people how to run away, hide, or talk through their problems instead of defaulting into face-punch mode. Cause you know what? The world needs more people willing to actually talk about things instead of immediately try to just solve it with punching, kicking, biting, and stabbing.
And the music tidbit? Why the fuck would I listen to music that just hurts my ears. I don't get that. Do you people listen to music that you find unpleasant? That's the same thing as forcing someone to watch a shock site. I HATE death metal and you know what? I don't care how much talent it takes to scream, if it hurts my ears and makes me wince I am not going to listen to it anymore.
