The original context of this thread (starting with user yequalsx's comment) isn't about "tighter gun controls", but rather the a complete ban of all guns ("I hope I am now seeing the beginning of the end of acceptance of gun ownership.") I think that is the scenario -- actual confiscation of all guns -- user purple-again was addressing ("This country is filled with rational, professional, well organized people who will kill before being disarmed").

This is different from outlawing or more tightly controlling certain classes of weapons, which seems to be what you're talking about. I think not being able to easily purchase fully automatic weapons or crazier stuff like rocket propelled grenades, stingers, 20mm cannons, etc is something a minority of gun enthusiasts grumble about but pretty much everyone basically accepts. Nobody that I know of is revolting about that, cops/feds have no problem enforcing it, etc.
