I just read the first 6 pages of this thread (I'm a slow reader and have to go out in a couple minutes, so I can't read it all). And can't find 17 people who said he was a retard for enjoying Mothership Zeta because it ruins the story.
Most of the posts related to story and lore are actually people saying that they have a problem with that and no one call Phipps names because he likes MZ when it has bad story. There might have been a couple posts that added nothing to the discussion and were just spam with images and memes. And there might have been a couple people who actually called Phipps a name or two (but this was when people were not sure if Phipps was a troll or not, and trolls don't get any love around here). But I didn't see anyone saying Phipps was retarded for liking MZ because it ruins the story.
