I find things like this fun to watch. But other than showing that some individuals are morons, they really don't prove anything. Now if they had shown a crowd and read off the positions and all the crowd agreed, then maybe would show proof of something.
Or something like that Penn & Teller petition drive - the fake one to ban dihydrogen monoxide (hydric acid) because it is so dangerous. The collected hundreds of signatures at some sort of health/green/eco fair. And you could argue that all that showed was that people tend to be petition signers. Although the comments in that indicate that indeed, most of the people just may be morons.
