Stupid people aren't really the problem. Someone who is genuinely thick will tend not to be particularly dogmatic and often will, given time, come round to the side with the best argument.
The problem is people who are intelligent yet intellectually dishonest (and there are quite a few). You'll find them on a variety of forums, pushing the line that God "could" exist, that there's no "definitive" proof against ID and so on. They misuse concepts like theory, doubt or evidence and in turn warp the entire argument.
