Jason, you're right of course, but you left out several classes of gun owner: nutcases, druggies, criminals, wannabe-traitors (militias), incompetents: the same classes do exist among photographers, but I suspect they're less a problem to their neighbors.
I've been shocked and infuriated by the gross ignorance of shooters at our very highly disciplined and beautiful public shooting range (Albuquerque). Lice who resent having to open their actions and dump cartridges when the range master orders it (in order to check targets).
Hang out for a few minutes in the gun dept at Walmart. That alone would create anti-2nd-amendment agitators if they actually understood what was being discussed.
I recently visited an archery/gun shop in Texas...had to spend a couple of days in the particular town...I had bow, boots, camo and gear in the car...I asked "what do you hunt around here?" It was classic south TX, just rock, stickers, and mesquite..I figured there'd be pigs and other varmints that would just require a cheap varmint license. The shop owner's answer to my question was, however, "Mexicans." Another class of gun enthusiast is what we conservatives like to call "bad people."
