Here's the deal: if you're satisfied with the state of the right to keep and bear arms in our country today, and feel like no one will ever try to erode the status quo, then don't join the NRA.
If you think every state should have shall-issue concealed carry, that people should be able to own handguns for self defense in crime-ridden towns like DC and Chicago, that the government shouldn't be allowed to unreasonably restrict your right to own guns for any lawful purpose, then, well, the NRA and responsible gun owners everywhere need your support.
Sam, PM sent. I'd love to take you up on the offer.
