The Second Amendment exists in order to prevent our balls from getting stamped. The government of California has clearly demonstrated its desire to stamp the balls of its citizens. Sadly, I get the sense that there are liberty thieves in the other 49 states who are eager to jump on the ball-stamping juggernaut.
Yes, even here in AZ, long a conservative holdout, there has been a trend toward increasing ball stamping of late (in general, not on firearms issues specifically).
