Neo-Marcionism alert @ Doonesbury

Over on Targuman Chris Brady has some excellent comments on a Doonesbury cartoon from the weekend, The Gospel according to Doonesbury. The cartoon falls very much into the pattern of Old Testament God is mean and judgemental / Jesus is great and mellow.  It is remarkable just how widespread this kind of neo-Marcionism is in popular culture, and I think it's useful for us geeky academic types to point it out when it occurs.  Perhaps we should get a little "neo-Marcionism alert" logo of our own together and bring it out on occasions like this.
