Your argument, is the precise reason why stupid people are running the public discourse.
There are some people who are just plain thick. They aren't presenting some sort of truth, because they haven't studied the subject and the basis for their arguments is paranoid crap like "The scientists want us to live in mud huts."

Black isn't white. The truth isn't somewhere in the middle with them both being grey. There are some times when people are just plain wrong.
