As I pointed out in another thread about another, NORML is a huge organization. There are die hard NORML supporters and there are those who say they are too wishy washy but they have made significant progress in many cases. Hooking up with NORML and getting on the mailing lists etc.. and attending the events does allow you to meet other activists and get to know people though. Can't hurt, and I wouldn't sweat the big brother thing.
