At the same time, it's a common mistake to believe that any argument that anyone is capable of making is automatically as valid as any other argument. Some arguments are simply more valid than others; there's no use in humoring people just because they think their unfounded opinion is as valid as any other.

Or maybe I should just defer to how Isaac Asimov put it: "There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'"
