I learned a new word the other day. No, you won’t find it in a dictionary, and in many ways it is too vague right now to mean anything, but here it goes.
Superconflation, verb. The act of attributing the actions of a single person to the whole of the group they are a part of or represent, and establishing a political ideology around it. Synonyms, are anecdotal explanations, unreasonable extrapolation.
It occurs in this way. 20 terrorists that happen to be Muslim fly airplanes into buildings and people superconflate that all of Islam is evil.
One crazy man kills an abortion doctor, and people superconflate that all pro-life believers are dangerous.
I’m sure you can think of many examples where people superconflate a single incident into an entire political position.
