Because people are batshit crazy. That’s all people do, just argue nonsense in their tribes. I like uk bball, you like Duke? What a loser! I’m a country boy, you’re a city boy? You suck! I’m super fit, you’re overweight? You suck! That’s all people do, just argue nonsense.
It is funny that the way we try to make sense of the things we can’t possibly understand are the things we fight over the most. Completely illogical. Maybe people just can’t admit they have no efffing idea.
