I'd argue mostly emotional, us projecting our different emotional experiences on each other and wanting them to feel how we feel regarding the same things.
I also believe it has scientific and legal and axiomatic components, just feel quite confident it has to do more with the fear, anger, guilt, shame, and other emotions we feel and attach to things.
Lol I agree. I think people who take maximalist positions often speak the most distantly about how they feel, using a lot of second or third person pronouns and focusing on how people certainly are and not how they might feel.
Part of that may be that feelings are a very difficult basis for constructive conversation if you disagree strongly. Even if you feel strongly, presenting your position as not emotionally based at least helps move the conversation forward.
