“mostly it teaches stupidity. Stupid weapons priorities, food and shelter, lack of military style training etc”
You mean like the first season when they were living outdoors and half the time no lookout was posted, and there were no tripwires or alarms. Why not find a nice defensible home that is now empty and live there instead of in the woods?
They had alarms in the season 1 camp. You could see them in the background, wires with empty cans on them strung between trees. They even got set off during the attack, problem is there were too many.
