Marx and Obama on Religion

From Bill Kristol's article here:

Marx said this:

“Religious suffering is at the same time an expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the sentiment of a heartless world, and the soul of a soulless condition. It is the opium of the people.”

Obama said this:

"And it’s not surprising then they get bitter, they cling to guns or religion or antipathy to people who aren’t like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations".
