I know it's an Onion piece, but they kind of have a point. Most people are not given ALL of the data before making a decision. As a result, we judge foreign policy/domestic decisions while not even knowing what is ACTUALLY happening.
I mean look, we don't even fully know the source of human sexuality (the jury is still out, and most studies done to this point have giant holes in them), and yet everyone has such a strong opinion about LGBT issues...
