One of my light bulb moments (while still in) was reading the Wikipedia entry on JWs, particularly a spot that stated that "...while JWs fought outwardly for religious freedom, they do not practice it internally..." (paraphrasing, but that's the gist), and I could not - in all honesty - refute it.
At that moment, I also realized two other things; A) it seemed very double-standardish (and therefore unfair) which bothered me, and 2) a critical statement made by an outside source is not neccessarily wrong and/or worthy of dismissal.
I don't know if the Wiki entry still has that bit; I haven't read it in a while.
