Brandon Ferdig submitted an opinion piece to the Star Tribune about science and political belief, writing that both conservatives and liberals are selective about the science they accept and reject. See "How Deep Have You Dug in Your Heels?", Star Tribune, 2012-10-16.
One of the items he wrote that liberals don't accept is "The science behind the safety of genetically modified foods."
I wrote a letter that was published today in response: "Food and Science, GMO opposition can be quite reasonable" (The Strib's title).
