I see the parallel you are trying to get, but I don't see a good comparison to a group that one must join to participate in the work place over one that is joined for recreation.
I would also add that members of the gun club would likely be in line with the political philosophies of the NRA.
Isn't the whole gripe of conservative union members that their politics differs with that of the union?
Sorry Dbroncs, can't quite get to the level of hypocrisy on this one, but what would the other political causes supported by the NRA be? Fiscal conservatism? Social conservatism? Gun owner rights I believe fall short of this on all accounts.....
