Does anyone expect to change the views of anyone through argument? What can happen is that there is a greater understanding of where the differences are, and in some cases a recognition of areas of agreement. At the same time we can get a better appreciation of what we believe ourself, and perhaps modify that. And we can hope that other people who are undecided may find our views convincing.

None of that is helped by throwing flak around, or slapping people around. And what relevance is that they might deserve it, when "it" does not in any way damage them?
