Personally, I have no problem with the NRA as an association of gun enthusiasts (me). Full disclosure, I used to be a member. It's when they inject themselves into our government by bribing politicians into passing stupid gun laws (or lack of gun laws depending on your perspective) that puts them on the side of evil.
A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed
Well regulated = sensible and logical gun laws, not the wild friggin' west. It should not be easy to buy a gun, though not impossible. it should be one of the hardest things that we American citizens should be able to do, like getting on POTUS's tee time
