“Bashiok”, a World of Warcraft community manager, wrote in a very nice way about why people act with vitriol on the internet.
One cause is a cognitive bias called projection bias. Essentially living inside your own head your entire life makes it exceedingly difficult to understand how others do not also live your same life, think your same thoughts, and hold your same beliefs.

We’re all guilty of this behavior. There are also brain-chemical reasons that exist to help us form tighter bonds with those like us (safety in numbers), but be antagonistic against those not like us (self preservation). We all do this to some degree every day.
