Everybody seems to use it pretty equally. Or mis-use it, I should say. If it is directed at a fellow Pub member, it’s a personal insult (/rules). If it is directed at third parties, it’s merely a disdainful label. While I don’t favor the term myself, I personally wouldn’t want to see speech curtailed to that extent. See it, move on. Every little thing doesn’t have to be retaliated against.
