Counterpoint - explaining things the other party knows is how you get on the same page.

I don't give a shit about your degree or your gender, it tells me nothing about where you're at. Most people are fucking idiots who have no idea how anything works, and that includes doctors and probably astronauts

And I say this as someone constantly underestimated. Yeah, it's annoying to hear things you already know at a basic level. I ask people if they know about things and take them at their word

But this is just normal communication. I don't know what you know, you don't know what I know. I probably understand how your mind and body work better than you do, because most people don't know how their mind and body work beyond a 4th grade level

Explaining things the other person knows is undesirable. It's also how most people reach the starting line for a dialogue
