"Right wing", "gun", and "nut" don't necessarily belong together. If you're interested in thoughts instead of labels, here's a couple -
Guns are not necessary for violence. Enemies foreign and domestic have done very well with box cutters, home made explosives, etc. It's the INTENT, rather than the tool, that's important.
I really, truly believe the general population should have the means and the will to overpower the "government" if it becomes necessary. We've done it sucessfully (18th century), failed at it (19th century) and there are some that believe it may be necessary again. This is the ONLY way that we preserve real freedom.
