oh my god. 'science' has been back and forth and up and down on coffee every ten minutes for decades. one thing i really hate is irrational people who don't accept science as the only arbiter of human belief. in this case as in so many others, rationality consists in changing your mind all the time and believing contradictions. well, believing what 'science' tells you at least requires a healthy continuous deferral to evidently arbitrary authority, which, as all obama supporters acknowledge, is the key to a future of relentless and extremely unfortunate progress, understood here as chronic confusion that makes you run around in circles.
