Someone already pointed it out, but "is" is singular, "are" is plural.
Anyway, it's not a redneck response, it's a personal responsibility response, one that says people need to own what they do. Let's go down your path where Whitey supplies all the guns and drugs to the hood to keep the black man down. In the world of personal responsibility, the black man doesn't have to take the drugs and he doesn't have to use the weapons.
You know, the black man from Detroit and Columbus bring a ton of drugs into Huntington, but I choose not to buy them. I own several guns, but I have never used one of them to shoot anyone, and never will unless they try to break in my house.
Something you can't seem to grasp is that the man in the mirror is always responsible for 99% of your problems and 100% of your solutions.
