When people allude to something but then become enraged when you ask about it, here is a totally made up example:
Poster: I totally disagree that family matter more than friends, my upbringing was the seventh circle of hell and if I never have to see any of them again it’ll be too soon, evil bastards.
OP: Gosh; what happened?
Poster: How dare you ask me that, I don’t need to justify myself to you
That kind of thing..
