Illhunter,
I didn't read every post after yours, but I have found the approach you take to be the most effective also.
Pro-gunners who try to argue with people who are anti-gun (who are most likely irrational and devoid of reasoning skills) are like those who would try to stop a locomotive by standing on the tracks, putting their hands out and expecting to not only stop the train (all 37,000 lbs of it -and that is just the locomotive), but expecting it to reverse course at the same speed instantaneously.
It is just an unrealistic expectation. A much more effective way to get the train to go the opposite direction would be to simply change the track that it is on before it gets out of the train yard.
