In the words of Billy Connolly, "Some people will never be happy as long as their @rse looks at the ground." The world has always had doom mongers and nay sayers. In days gone by they would sit at the end of the bar with a little rain cloud over their heads, generally being avoided by most. Unfortunately the era of the world wide web now gives them a world wide audience for their negativity. As Racedo says, the mods will periodically banish a few for a period of reflection and sanity returns.
