I would submit that those folks know that "assault weapons" are fully automatic, and not the gun-controller/media's false holding of semi-automatics.
And I submit that this poll is full of sh**, at least the part about the 59+ group. All the people I know in that age group(including me)grew up with guns and are all for the 2nd amendment. In fact many of them take exception to the term "allowed", we are guaranteed the right to keep and bear arms, the government does not have the right or the power to either "allow" or "disallow" our ownership and use of firearms.
