Reasonable argumentation is a precious social resource that we should cultivate, promote, and protect. I think you express a view common to many here, and I hope this forum is able to continue fostering a culture of reasonable disagreement over combative, substanceless posturing. I happen to agree with the commenter you responded to on many points, but also found the presentation combative rather than constructive. I second your appeal to use more precise language, although I sympathize with the anger implicit in the poster's comment.
