And that's the real bitch of the situation, and why I wondered earlier in this thread about his upbringing.
I acknowledge Jason is an adult, but for the purposes of empathy and understanding, I don't think it's intellectually honest to just go "He's a dick!' and move on. As we saw in the Dr. K video, there's some kind of mental immune system kicking in when he feels like someone says he might be wrong or even worse (to Jason, anyway), he could be right and people would still be upset.
In children, this behavior can be indicative of a dynamic at home where one or either of the parents might do that thing where they say "Your feelings don't matter, what matters is the facts." and then the kid expects the whole world to work that way, and gets upset when they're expected to behave differently. It can feel unfair that at home your father might say "It doesn't matter that you're upset. I'm correct. Here's why. See?" but then at school the teacher tells you you need to apologize to Britney for hurting her feelings when you told her unicorns aren't real.
