I could break stuff down to you but I won’t because I have shit to do and there’s textbooks. Also your eyes would glaze over 2% of the way in. So in that sense, I can’t, because I can’t make you actually want to understand it. Best I can do is hand-wave and rely on you not understanding why my explanation falls short of actually being one, making you think you understood something.

Talking shop and obfuscation are not the same thing but are generally indistinguishable for the uninitiated. I guess what I’m mostly miffed about is the implication that’s going on in OP’s erudite thesis and your anecdote: That people who talk about stuff you don’t understand do it to exclude. Maybe, you know, stuff is just complicated and needs years of study and practice to understand. It’s not a status thing, someone with a Ph.D in chemistry will have quite a task ahead of them understanding what hair stylists are talking about when talking shop about chemicals unless they themselves happen to specialise in that area. Now try explaining conditioner chemistry to a philosopher, instead, it’s probably hopeless.
