Jonathan Haidt on Food

An amusing passage from pg. 13 of Jonathan Haidt's book The Righteous Mind:

And, why do so many Westerners, even secular ones, continue to see choices about food and sex as being heavily loaded with moral significance? Liberals sometimes say that religious conservatives are sexual prudes for whom anything other than missionary-position intercourse within marriage is a sin.  But conservatives can just as well make fun of liberal struggles to choose a balanced breakfast - balanced among moral concerns about free-range eggs, fair-trade coffee, naturalness, and a variety of toxins, some of which (such as genetically modified corn and soybeans) pose a greater threat spiritually than biologically."
