I gave you many chances to answer your own question Nosmo. Now I will answer. I didn't up til now, because I wanted to just get to your stupid answer.
An assault weapon's PRIMARY purpose is to supress an enemy. By delivering a large number of rounds down range, the enemy is forced to take defensive positions. This allows other troops to engage the enemy with sniper fire, grenades and other weapons to wound, kill or force a retreat of the enemy.
Thank you. Are the virtues you described so important that such weapons should be in the hands of civilians? Have civilians enemies to suppress? Do civilians have the need to deliver large numbers of rounds down range?
Should America be forced to accommodate such weapons by arming school personnel, posting armed guards in stadiums and arenas? Why should America be forced to make room for such weapons if civilians don't require them? Is the privilege to own such a weapon greater than everyone else's right to live free in a world not threatened by them?
Yes, protection is very important and since criminals and tyrrants rarely care what the law is, a necessary part of some people's right to be protected. The possibility of your right being lost is not grounds for terminating the rights of others. Imposing your will on others is not a right you hold.
Take the bank robbery in LA several years ago as a case study. The police had to go to a gun store in order to stop them. Now you want to take those very weapons away from everyone, except the criminals. This is the real world, not Nosmo fantasyland.
