Thank you for so eloquently illustrating my point.

Obviously the argument that unregistered Guest,Bluesman is trying to start here has nothing to do with a disagreement. It is a personal attack. Note that he does not criticize the post, but the poster. His problem is not with what I am saying but with my very existence.

I guess one could say that the disagreement would be that he thinks that I should not exist and that I would presumably argue that I should exist. At the very least, this should qualify as an existential argument.
