How important is it for all well-educated people to know and believe Theory of Evolution?

Despite all the hullabaloo about “scientific literacy,” the only reason the cultural left cares so much about evolution is to disprove the Bible so they can stamp out the belief that there’s a God who cares about whether people have gay sex. If it weren’t for that factor, evolution would be something only nerdy eggheaded scientists cared about. It would be important in biology classes, but outside of that, for journalists to go around asking Republican politicians if they believe in evolution would be like asking them if they believe in string theory.
