I agree with you. And I think it's disgusting and sad that people blame the "object" instead of the person behind the object.
However, we don't have the monopoly on being right, our side doesn't float in a cloud of its own righteousness and perfect facts. Both sides are right on some points (I know, I know, blasphemy!). I'm pro- gun because to me this side makes the most sense, it's the most rational and is supported by the most facts.
BUT, make no mistake, guns ARE part of the problem. They're just not cause of the problem.
