> Is it a "let's talk everything about guns"? Is it a "let's go to a shooting range and shoot guns" club?
I know of no club where the purpose is merely to talk about guns. Gun clubs are typically organised shooting ranges. In Australia, if you own a firearm, I believe you are legally required to belong to one, and have some kind of minimum attendence per year.
And yes, they discuss politics, and they veer strongly towards conspiricy paranoia.
I expect it's the same in the US, especially with its NRA stranglehold the culture there.
I'm not sure if you're aware of the Port Arthur massacre in the 1990s in Tasmania. Probably small beer if you're from the US with it's weekly atrocities. The PM at the time instituted a mandatory gun buy-back/hand-in/confiscation scheme to reduce the number of firearms in the community, which was broadly seen as a Good Thing (by people who don't own firearms. ie. the majority of the population).
Talk in the gun-club is that the massacre was conspiricy perpetuated by the Gubmint in order to bring in tighter gun control laws, confiscate firearms, etc.
