Obama told an evangelical church in South Carolina: "I am confident we can create a Kingdom right here on Earth."The idea that human society is perfectible ("Kingdom right here on Earth") is common among liberals. This failure to understand human nature is why their policies usually suffer from 'unintended' and sometimes quite disastrous 'side-effects' despite liberalism's loudly proclaimed 'good intentions.'
Separately, and in the same speech, Sen. Obama claims: "At least in politics, the perception was that the Democrats were fearful of talking about faith." This is delusional: Democrats have not been "fearful" of talking about faith. They have talked much about it, mostly about how they despise such superstitions and how Christians, as they see them, are intolerant. Intolerance was in fact the claim that Obama used next in his speech talking about "Republicans who had a particular brand of faith that oftentimes seemed intolerant or pushed people away."
