Another plausible interpretation of TF's flip-flopping is that a month ago, xe was here because xe thought it was a fun community, and then xe got "converted" into an earnestly zealous and quite naive Singularitarian. Much of TF's vitriol, then, would implicitly target xer lackadaisical past self in order to (consciously or unconsciously) distance xer current self from the pre-conversion self.

Mind you, I'm not checking TF's history myself, so this might be a bad guess. I'm just pointing out a pretty plausible alternate hypothesis.
