What I generally hate are fanboys. They will blindly ignore your opinion to make their brand (or whatever) sound better, and that you feel like your missing out.
I had an argument with a friend of mine (gamer). I brought up the fact, that I was using Linux at that time. It triggered a huge argument, it literally turned into a war.
And the most annoying thing was, that he ignored my solid facts about Linux, things like:
"Many Linux distros have a packaging system that is far superior to that of Window's"
He replied, by stating that the Window's updates are more superior.
Kill me.
