Dig,
I'm not sure it is possible to say that the NRA is comprised of any specific type of majority, rather it is made up of what can only be called Americans, though I'm sure there are some foreign members too. It caters to multiple interests with the common thread being firearms and it is substantively inclusive rather than exclusive, as is proper. That same multi-faceted perspective in all things firearm related causes the NRA to be unpopular with some. For those persons, it is still possible for them to send a contribution to the NRA-ILA [Institute for Legislative Action] and they will never get so much as the first solicitation to become a member, they will receive no magazine and the money sent WILL be used toward favorable firearms legislation and second ammendment protection.

Their snail mail addy for anyone interested is:

NRA-ILA
11250 Waples Road
Fairfax, VA 22030
USA

BTW, with the Pound Sterling at two bucks, I'm sure they would be happy to have any contributions from our good friends in the Isles, it will help to insure that we retain the right to buy those wonderful Brit doubles that are held so dear on both sides of the pond and anywhere else that fine guns are appreciated. They will come a bit more dear too, at the current exchange rate, ya know;-)I think it would be quite fitting for one of your field guns on the queue for a re-stock to sport an NRA-ILA sticker, a fine badge of honor, that.

All the best, my friend,
tw

edit: for those concerned this was NOT written as an exclusionist note, rather it [NRA-ILA] is a place that provides a known good 'bang for the buck'. I too have raised monies for other orgs that interface with wildlife and shooting sports as well as becoming a member of some and supporter of others. Heck, I've even taken members of both parties hunting, but not at the same time. And I don't think the world is flat, even though it mostly is once you're up on the caprock. I prefer the Wichita breaks myself.
