After shutting down all science projects that involve projectiles, we need to move against other deadly militaristic skills.
1) stop all activities that train for grenade throwing.
For example, one so-called sport has a group of five taking turns attempting to throw a projectile through a 'hoop', where it should be obvious to anyone that this is training terrorists to hurl molotov cocktails through the windows of our leaders homes as well as elementary schools.
2) stop all activities that train for Hoplite style of battles.
For example, one so-called sport has a groups of eleven engaging in pushing and shoving to get a ball to a goal behind the group.
This is clearly military practice to train for close quarters combat without firearms. No doubt their plan is to disrupt the police who may be engaged in clearing streets from deranged people such as the occupy Wall Street protestors.
3) debate clubs. Why do we need debate clubs except to train people to delude and confuse the populace? The government licensed media should provide all the news and opinions we need.
