While I understand the desire to have a discussion regarding the relative merits of various versions of Dungeons and Dragons (or whatever), I think there's a very, very thin line between "criticisms levied in edition wars" and "edition war posts".
Here's an example from the thread posted in the OP: I'm genuinely curious what the intent of the poster that compared 4e to WoW was exactly. Is there really any new ground to tread in that area of discussion that hasn't been hashed over a million times before in the last four years (in edition wars, no less)? Seriously, is there really anything interesting or new to discuss there? How about that 4e is for babies and simultaneously too complex? All of these things were implied in that thread very strongly by the images presented.
It seems to me the only possible purpose of the thread is to show the poster's preferred edition in a positive light while implying that the worst of the complaints levied against the non preferred edition are actually true. Only the poster doesn't have to explain anything or back up any arguments because it's only a picture and it's only "my opinion, man!"
Well, guess what? Opinions can be (and often are) wrong and posting this stuff as an image might give you plausible deniability but don't have a hissy fit in a forked thread when people call you out on your shenanigans.
