Non sequitors.  The statistics say the most guns are bought by conservatives, not progressives. Do I think people who shoot other people are making a decision.  Yes, all across the board.  The most intelligent decision I have heard about gun use lately came from a C&W band who had concealed weapons in their bus during the Las Vegas shooting.  They chose not to get them or use them because it was their death sentence at the hand of police and they also knew they might very well have shot innocent people themselves.  It changed at least one band member's view of gun ownership 'for self defense'.  That is a personal choice I agree with.

You are making a very big deal about personal choice when it comes to guns, but I get the distinct feeling that your idea of personal choice is somewhat limited and aimed at criminal use.  Most gun deaths are not from criminals, but from family members, significant others, and suicide.
