The Second Amendment protects an individual right to bear arms, as the U.S. Supreme Court will decide (I think). That right is predicated on, among other things, the need for private citizens to protect themselves against an overbearing state. The overbearing state, in this instance, is the State of New Mexico -- its Human Rights Commission to be precise. Praise the Second Amendment and pass the ammunition.
P.S. Here's another relevant case, also involving New Mexico. (It occurs to me that the adjective "New" is window-dressing. Mexico is Mexico, even when it's dressed up as "New.")
