This is just my personal opinion, but I believe that bands that "play in the name of god" are exploiting Christianity. I'm not saying that they do it consciously (although I wouldn't be surprised if some do), but when you have a message that says "We believe in god, and our band is dedicated to playing music devoted to Jesus", I think that you can get more people to buy a poorly produced or not artistically talented record as long as it is "for Jesus". Now I'm not saying that Underoath is a horribly untalented band (in fact I find their drummer to be particularly talented), but I just don't enjoy the possibility of bands exploiting something that may be very personal to a certain group of people (myself not included). And I guess the fact that I can't stand listening to bands that sing about god, but that's just because I'm an Agnostic.
