The problem I have is how uneducated all the "Ban assault weapons" advocates are. They insist upon banning "AR-15s and all assault weapons" when in reality, its an overglorified hunting rifle with a pistol grip and an adjustable stock. I literally have a Ruger .22LR that is the exact same as a commercial AR-15.
Not to mention, there are firearms on the market that are ten times worse than an AR-15.
I honestly can't imagine what they will say when someone devastates a venue with a semi-automatic shotgun, and if they so choose to use buckshot or some other type of scatter, the farther people run away, the more people would get hit with one triggerpull.
