It's actually part of being on the internet and how that affects your personality and perception. Think about it, you practically have access to every tidbit of information ever to exist. Of course you are going to assume that you are right and everyone who disagrees with you is wrong. It's human behavior. If I am typing something from a computer I can check and see within seconds if I am right or wrong so my confidence and ego blast through the roof. That is all. :)
