Which was precisely my point: in your rush to denounce Bob as obviously ignorant, you neglected to identify what you thought he was ignorant about.

Now you concede that he might not have been ignorant at all, but just using a word ("migration") with a different meaning than what you had **assumed** it should mean.

How about clarifying meaning BEFORE rushing to judgement? That way, you won't leave OP's seeking actual insight stranded in a sea of rhetorical denunciation. Received on Tue Sep 25 2007 - 19:00:30 CDT
