Not in this case, but sure, if I am self-critical for a moment, I think it sometimes can happen that I post stuff to get a reaction, but it's more done sub-consciously rather than intentional. So I do not admit to trolling, but I think the basic psychological mechanism - the urge to want a reaction from other people - might be similar.
About GeneralMLD, the key thing is that he is the underdog. That's what the Xbox-Sony fanboy war is mostly about from the Xbot perspective. We are many who hate the superior attitude of Sony fans, not Sony or its products themselves, and that's why we have sided with the underdog and sometimes we take on the full fanboy role of pretending Xbox is the best thing since sliced bread.
But you can see the blink in the eye of GeneralMLD. He is not dead serious. He's just a lonely hero standing up against the fanatical Sony army.
If that's how you see it. I sure as heck don't see anything heroic about righteousness as an "underdog - one man army" in an online forum, especially when the plight is stained with irony.
