This is going to be meta as fuck -- but the only preconcieved notions I brought to that post were; that the gist of his complaint(and thus post) applies to just about everything(which a later reply addressed) both on this site and within western cultur, that Iraq is a contentious topic(confirmed by some of the replies), that bringing up your own US military service invariably will send any conversation down certain lines(also confirmed by the replies - thank you for your service, what were you expecting, yada yada), and that as a poster with an ID that low, he knew all of these things and thus knew what he was doing. And of course what is implied by the fact that both darfur, and Rwanda 2, child of rwanda, aka the congo were brought into it as well.
It was utterly irrelevant to the article(or rather only as relevant to this topic as to any other topic), only sort of relevant to the person he was replying to, and not productive except to create a derail, which it did. That's a troll -- oh, and the purpose of a troll is to generate conversation, not necessarily in a bad way. I know that definition has gone out of vogue, but sorry it's the one drilled into my brain.
