As I watched it, I was frankly pretty appalled. I hear arguments like this all the time and almost always from people who have no idea what they're talking about. I was ready to write up a rather scathing review, deconstructing the rapper's entire argument, but then a colleague of mine in Kansas City - Scott Chrostek - posted the following link on facebook. The link is to another blog written by Alan Combs (yet another UMC pastor) who pretty well summed up everything I wanted to say. So, here you go.
