"Utopia (from Greek i.e. "no place" or "place that does not exist")" I think maybe it was a joke? A continuation of the original punning? I didn't see it as an attack, at the least.
Ok, so that part was a pun, the rest was an ad hominem attack. He referred to me multiple times and never made any mention of my arguments - it's an excellent example of an ad hominem attack.
