Karl, the point I would like to make is that using any logic will fail when it is up against emotional arguments.
So what else can we do?
I'm not going to lower myself to use their methods (although it could be fun). It is morally and ethically wrong to do so. Besides which, the real anti-gun opponents are only using emotion as a cover for their agenda. They know full well that they have no logical ground to stand upon. Hence the need to use emotional tragedy as a cover.
