I think we have to do that too! I have encountered this animosity over disagreement in politics. We identify the person with an abstract idea, dehumanize them, and can so more easily hate them.
Perhaps we could add a layer of thought to this - our feelings about a concept are shaped by current cultural norms and teachings. There are so many layers to our understandings. I could ramble on all day about this. Thank for starting the discussion.
Sorry about those massive downvotes - evidence of exactly what you are saying. Even your innocuous concept, in this case to allow ranges of thought without hate - can elicit harmful and hateful actions.
Strange times these.
