You would be a fool to think that an entire population is stupid. Perhaps a proportion sure but the deciding vote comes from a large proportion of the population that are by no means stupid. Democracy in theory is a form of distributed computation and just because you don't agree with the end result does not make every else stupid
So you are saying people who think other people are stupid are, in fact, the stupid ones. Fascinating.
What would you say if most of a population think that most of the population is stupid, themselves excluded?
Which seems to actually be the case quite often.
