I'd go beyond that, and say that the whole point is to ridicule--to find someone who doesn't know the score--do a gangup organized by IM, if they even need IM--and then high-five one another a la Beevis and Butthead.
And there's the uncanny similarity in discourse--the same one-liners over and over. "You need to get back to biology class." "You've lost what little credibility you ever had."
How is it, too, that they can show up on a thread, en masse, so quickly?
In sum--these engagements are in bad faith. They are not for exercising the restless arguing muscle ( a motive I assume of most arguers here, since it's my own motive)--they are a means of exerting control and domination over others. Yes, a kind of fascism, albeit rhetorical and limited to online exchange.
The "virtual ignore" thing appears unique to evos--at least, I've seen it nowhere else but from evos. In eight years, I've only asked one poster to leave me alone because he was calling me "Satan" and I thought him deranged (he wasn't an evo).
And don't forget "why do you lie", "your a liar" etc.
