Why are so many people so stupid on here?

There are so many people that ask the most stupid fking questions in the world, is it trolling ? is it just plain retarded? I realize that the USA is filled with idiots and that's why our economy and everything else is nothing but fail. The TV is a major cause of it since it pretends to be the ruler of everything and it's nothing more than a bunch of bullshit to make money, but all the fking idiot kids out there don't realize it and think it's actually important. So my question is why is everyone on here retarded?
