So this thought has crossed my mind many times and again today when someone replied to one of my comments that is so bad it doesn't even dignify a response and I still don't have a good answer for.
We all know that calling someone a fanboy here is an insult and I'm am absolutely cool with that rule and support it 100%, but there are people that are just fanboys. They can be in absolute denial about everything, blindly follow whatever it is they support, and think everything else is terrible even when confronted with absolute proof they are wrong but will still end up saying they are right, you are wrong.
So what do you call these people should you actually have to interact with them?
