I’m aware of the term Christfag. I was there, Gandalf. 4chan also had an incredibly abrasive board culture as a means of social filtering, so {append}fag was their way of referring to someone who had identified as some way, or else for someone to refer to themselves as that thing, usually because they were trying to tell everyone they had unique perspective on what was being discussed. It got to the point where I saw a person open their post identifying as a “Gayfag.”

I don’t like using the term for this because its punching down at an actually oppressed minority who would be caught in the crossfire.
