I get he's trying to reach out to leftist atheists but that hardly made any sense. The lies of government are inevitable and have nothing to do with religion or mythology. When Jefferson said: The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants; it becomes abundantly clear tyranny is cyclical and there's really no such thing as perpetual "liberty", a lion doesn't stop fighting for it's food, nor will we ever stop fighting for our beliefs and survival.
It's an issue of ethics because the Obamas, and Gingrichs, and Romneys, are all very logical people-- they do what they do to survive, make money, and have power, it's their ethics that should be called into question, politics makes sense to any rational person, follow the money trail.
Government can be used for good and evil, so can religion, and so can atheism just look at the Chinese, or Stalin. So I wish people would stop making false comparisons.
