I don't engage with this poster because of his past dishonesty, i.e. misrepresenting my posts. If anyone not on my *(&^%-list is curious, I am happy to provide references.

I applaud your decision to not engage (as a good general strategy given your state of belief---the specifics of the conflict do not matter). I find it usually works best to do so without announcing it. Or, at least, by announcing it sparingly with extreme care to minimize the appearance of sniping.
