I really have a problem when public personalities are castigated when they say something, which may be their personal opinion, which isn't what the audience want to hear or its considered in bad taste.
Celebrities are people too, and they can say stupid things and sometimes forget that they are in the lime light, being watched all the time.
Oberst was being a dick, but let him say what he wants to say, if you don't agree with what he says, don't listen to him, and so long as the music is good i don't think theres a problem.
This topic actually reminds me of something that happened in Australia, Darren Lockyer, the Australian Rugby League captain said a joke about the Bulldogs, which i thought was absolutely hilarious but, the amount of shit he got into was amazing.
Also, i think Live 8 was an absolute load of bullocks, they made a big deal about how none of the performers were getting paid, but were given gift baskets worth between 8 and 10 thousand dollars. I think there are better ways of swaying government opinion than holding a concert. Hence my dislike for Bob Geldoff is shown.
