Pat would be a legit compelling writer if he himself were a character he'd created. He shares that quality that Trump has where his use of english is so idiosyncratic that, regardless of how you feel about the guy, it's genuinely enjoyable to mimic his style.
The entire breadth of what Pat is can be understood by witnessing the briefest exchange between him and another person, but he has nested depths of retardation that keep him compelling to study for the long haul. Most lolcows followings have the air of a secret shame cult, where you have to study a lot of lore to really get into following the lolcow, and it looks bad enough to the casual observer that nobody wants to let people they know IRL know that they are into it. Like imagine trying to explain why you follow KingCobraJFS to anyone irl. Nightmare scenario.
But with Pat it's like he's his own elevator pitch, you can convert someone into a patposter with just a screencap of him threatening his own toilet with prison time. He's not medically retarded, he's not any type of minority anyone would feel sorry for, he's not in desperate poverty, he's just an awful little man who is awful in a very funny way. Like Rekieta he really had to grind for this view.
