Problem with surveys

I've heard it suggested that surveys are biased towards the more extreme opinions, that they don't take into account the opinions of the apathetic.  A recent survey taken across the majority of the United States has shown that, out of a test group of around 1100 people, 100% of them performed surveys.  This would seem to show, beyond a doubt, that surveys represent the entire spectrum of subjects.  As such, any error during a survey would be solely caused by the person performing said survey and not by the nature of surveys in general.

I'm convinced

BASED ON A NEW AP SURVEY, 100% OF PEOPLE PARTICIPATE IN SURVEYS!

Do a series of surveys, and as the sample size increases, the mean of the distribution of the results will tend towards the true mean.

My first 10 test surveys have showed a promising trend, with the sample distribution seeming to remain at 100%.

Having endeavored to create the largest survey survey, I will survey to find out the region wherein the largest population density exists.  This will be done by surveying everyone to find out where they reside, thus surveying the population density.  There, I will perform a survey to survey who takes surveys.  This will optimize efficiency, and allow me to get an unprecedented sample using only minimal effort.
