That is a poltard meme which is even more grating because I'm the one who invented it when ripping into the moronic herd mentality of right wingers on KC many years ago. Similar to how they stole wojak and turned it into some retarded faggy american political partisan symbol. I would just like to note that it was specifically hyper partisan right wingers that I was using NPC for, namely because of their empty brained knee buzzwords and sloganeering to the point where any discussion on a shithole like /pol/ is exactly like the experience one has with the same loop of several phrases of text appearing above non-character NPCs in a crpg, the overall effect being an eerie sense that these people are not even human and in many instances literally can be bots.
The article itself is an exercise in futility and a good example of the saying that a philosopher can see the universe in a grain of sand (and conversely, you can beat a dumb motherfucker into a coma with the library of Alexandria and he will have not fundamentally changed his state). He doesn't even seem to get where "feels guy" originally comes from, or the fact that its misuse is basically like that one comic where someone is on the bus trying to interpret the image and concludes he is sad because he has cancer. The author of this article is seemingly two steps away, rather than one, from the original meme, being essentially another example of the "how a fandom is destroyed" stick figure comic or more generally that terrible mix of the curse of eternal September and all the idiotic bydlo who do not understand memes and hence destroy them; in perhaps the greatest irony, the worst destroyers of memes being now the poltards themselves, who maintain exactly the same total lack of self insight.
But moreover as I said, I am personally the one who started using it in a pejorative sense specifically against rightards who seem not to appreciate the irony of the fact they have coopted "NPC" as another of their very brainless buzzwords for which I was mocking them, alongside the usual "cuck" "JIDF" "SRS" and so on one buzzword responses they often gave to any disagreement or critique. They are essentially flashy robots who are only good at slogans and buzzwords, but this is the same behavior largely described by such terms as "sheeple" and which has been described more or less for centuries which is the herd mentality of dumb peasants who are lacking in both education and native intellect. In a modern sense, one would call them creatures who, given an online format where text is the only input/output, cannot even reliably pass the Turing test. Speaking of which it has occurred to me the great folly of still using imageboards rather than setting up a blog or LJ or whatever if I'm going to keep bothering to post online. For one thing, it would help prevent the Chinese whispers, which is only marginally useful in a "wartime" scenario where you are camouflaging yourself among the largely adequate masses and using the voices of others as human proxies.
