Troll is using the same tactics tobacco companies used in their lawsuits. Obfuscation, cherry picking, character attacks, missrepresentation, delibaretely misleading statements etc etc. Scratch below the surface and there is no substance to his posts. No rational analysis or counter arguments. Given all that, it's completely reasonable to label him as a Troll and ignore him. Besides the fact that you'd miss out the fun of watching him get humiliated day in day out.
