There should be a word for what people mean when they say disinterested and don’t mean disinterested. Disinterested means something similar to impartial- you don’t have a view and can arbitrate the debate fairly. What people seem to mean is that they have an extreme form of negative interest in a subject. Uninterested doesn’t quite cover it, that seems to be to the concept of interested what amoral is to moral.
I’m talking about a vehement anti-interest that leads people to complain about the thing they lack interest in existing, and leads them to resent and despise people who are interested in it.
