Well, just for the record, I'd like to acknowledge that being pious does not necessarily correlate to attending church. It's an indicator, to be sure, but there is no correlation.
Far more important is that relationship that one has with the God of one's understanding.
But deliberately portraying oneself as being pious or even respectful of religion when one clearly isn't transcends normal behavior and puts one right out there as a liar. Mr. Mannn is completely correct in saying that Barry will use religion to further his own aims and his own aims involve him and his (aka Ayers') agenda.
Ergo, Barry is a liar. Furthermore, the First Wookie is a liar too.
