I'm not a moderator here, so I might be overstepping my bounds, but... I can't think of any instance where you actually need to refer to any group like that while discussing content of the game. Whether someone is a fanboy, troll, whiner, etc., shouldn't matter about the information being posted. If it's something that is obviously trying to bait someone, insult, harass, etc., then report the post and let the staff deal with it. Calling people out, and addressing it while in the thread only serves the purpose of such a post; that is to derail and throw a perfectly legitimate discussion off track.
So, just report posts that you feel are inappropriate, don't reply to them, and certainly don't drag yourself down to the level of name calling, ect.
