That blob is (ironically) extremely ideological/generalising. Doesn't mean I don't disagree with it though, maybe just the approach/tone.

I believe you may be grouping strong (and maybe not always right) opinions with flat out chaotic evil trolls (whom there are actually extremely few).

It's been intruiging to grow up witnessing the appearance of the term "troll", initially designated to IRC and other net spammers, to it's present and increasingly meaningless, nebulous definition of "mean people on the internet". It's a big difference, which your linked blob quite interestingly evidences :D
