Been too busy to waste time argueing with a brick wall. Sorry.
The brick wall idiom is one that goes two ways, and speaks as much for the argumentative nature of one who argues with the wall, as it does about the inflexibility of the wall. If arguing with a brick wall entails making unsubstantiated claims, condemning logic in favor of emotion, presenting inaccurate supporting reference, ignoring when those things are pointed out, not answering the questions one presents to others, all the while claiming one doesn't actually care, then yes, it's a questionable course of action. You've taken four approaches to this discussion, trolling, humble personal opinion, factual logic, and emotion. The successful one was the personal opinion, no one even responded to it. There's plenty of people who believe guns are dangerous and largely unnecessary, who also have no interest in supporting legislation to control the lives of other law abiding citizens.
40000 gun casualties a year yet to to be explained away.
Once again the number presented is inflated, so thus incorrect according to current reliable sources of fact. No one has tried to explain it away.
