Liberty and Justice for Guns

Each time I drive past a honky-tonk bar and see a pickup parked outside, complete with gun rack and a bumper sticker that reads something like PROTECT YOUR SECOND AMENDMENT RIGHTS, I ponder:

1. Why isn't the owner of the vehicle concerned about the first, fourth, fifth or eighth amendments?
2. Can the owner explain what a "well regulated militia" is?
3. Where is the Second Amendment found?
4. Has he (I guess it could be a she, but somehow, I doubt it.) ever read the Constitution or the Bill of Rights?
5. Does the displayer of the bumper sticker see anything contradictory about referring to the Bill of Rights of the United States while sporting a Confederate battle flag window decal?
