I've heard it said before, yes. By people who have no idea how much the NRA would love if every American trained for a concealed carry permit.
"But Reagan and the black panthers" comes the frequent reply. You have to understand: The NRA was a radically different organization pre-1977. There has been a massive change since the Cincinnati revolution (or revolt, depending on who you ask)
This isn't what would realistically happen?
Can you talk some more about this NRA revolt in 1977?
