My dad was an NRA member. I can tell you from experience that the NRA and their members are all about safe & responsible gun ownership. They know that irresponsible ownership threatens the future of their rights. They provide safety training courses all over the country.
I don't agree with everything the NRA does, but they do a lot of good things too.
