I doubt he will read this, but...
Ignorance is bliss, you must be blissful.
As the founding fathers said, a people that fears the government is tyranny, a government that fears the people is freedom. Your ignorance of weapons notwithstanding, you also need to research what the 2nd Amendment is for. It is a check and balance, designed to allow the people a credible threat/defense against crime, foreign invasion, and THEIR OWN GOVERNMENT. This is not for revolutionary purposes, it is designed to ensure that the government does not attempt to oppress the people for fear of revolution.
Gun laws do not positively impact crime. Most gun crime is committed by juveniles (<21 years old) with HANDGUNS. By law, the posession of handguns by these individuals is a crime. Criminals do not obey laws, and therefore making a gun illegal is like making murder illegal; it does not stop it, it makes it just makes it illegal. However, areas in this nation that have laws allowing citizens to go armed and defend themselves have less crime, because the criminals are deterred by the thought of being shot.
Last point I have time for. Even if banning so-called "Assault Weapons" would cut crime, the past AWB only banned cosmetic features of weapons, therefore could not have had any impact on crime as there was no shortage of weapons being sold with the exact same characteristics as "Assault Weapons." So any claim by liberals that the AWB helped deter crime, and now their will be an increase in crime is bogus.
