text: 1.   Most of the population in the US grew up before OKC or Columbine.   Prior to those events firearms explosives and propellants were talked about freely even in suburban and urban schools let alone rural schools.   Anyone saying otherwise is flat lying.  We haven’t banned physics and STEM rocketry classes so it’s still discussed today.  
  
  2.   Most explosives ARE simple explosives and most definitely can hurt people.   However a couple simple demonstrations with simple fireworks taught a healthy respect for even small explosions especially in confined spaces.
  
  3.  Thank you for using moot correctly.
  
  4.  No you missed the point on licenses.   A license LEGALLY ALLOWS a person to do something.   Not having a license does not prevent anyone from doing anything.   And if you want to argue ‘regulations’ you don’t have to pass a background check to possess a car.   A license is far less restrictive than the background check.  Again you lost on all points (except minor grammar).
