I'm not a religious man and am in fact, an explicit atheist, and yet I find this comparison offensive on many levels.
The first and most obvious point is that it is a stupid, stupid, stupid comparison only to be made by people so ignorant of religious tenets and political tactics that they actual think it's a clever idea. Do they not understand the concept of blasphemy? Does it not occur to them that Christians might, just might find this a bit offensive. Do they think that average voters might not want to worship their candidate? Nope, at least the dailykos doesn't think so.
The second point is that it's factually inaccurate and reeks of nasty elitism. A community organizer is someone who goes out and lobby's the community to support some project or political agenda. They are either mercenaries or true believers. Jesus was supposedly the word of God - truth. It might have been fair to compare one of the apostles or missionaries to a community organizer but Jesus?
The last point is that it's just creepy. I don't worship anyone and I don't want too. Obama isn't divine and he isn't salvation and he isn't a damn prophet. He's a fucking politician and what matters is his character, judgement, and ideas and when you take a look at him, he isn't the truth, he's just another politician.
This is why Democrats lose nationally. Like Mrs. Kael they simply don't understand the country they live in.
