What do you mean by astroturfing, then? At this point I don't even know what I'm being accused of. I linked to the Wikipedia article because according to the usual use of the term 'astroturfing', it doesn't really make sense to accuse someone of astroturfing and yet deny that they are working as an agent of an organization of some kind.

Again, we could easily resolve all this with a phone call, if you were actually interested in the truth of the matter. But I guess you'd rather hide behind your online persona and cast false accusations around.
