If you do believe in science, you really have to actually stand up and make a stand for it. You can't just say, the facts aren't in. Science is always looking for better explanations to everything, but that doesn't mean that when we get on a plane we don't know what's supposed to happen next. And if it doesn't go the way that it's planned, that's a big, big problem. The culture wars are very tricky and make me a little sad.
