This is my favourite facet of fatrick's personality, it's something that pegs him as proper lolcow.
His unwillingness to even consider other people's points of view and complete refusal to ever admit being wrong, even when irrevocably proven to be, is why he will never ever improve.
You see this with many different cows, and that self-righteous self-important smugness is beyond infuriating, which is why they start to have a hate following.
I love his general assholery, whenever normies stumble into his tweets in the wild, you can see the evolution from "this guy's a retard, lemme try and educate him with fax and logik" to "I want to waterboard this corpulent faggot".
It's a great source of keks
