Do you have a kind of "What has been seen cannot be unseen" feel about this? For me, once I noticed this behavior in people, I now see it constantly, and not just with politics, but with any idea that supports the categorization of humans. And I think it's particularly sneaky, because it seems like people who do it perceive their thinking to be logical, due to it containing logic, which is a similar error.

I wonder if there is a way to fix this problem, kind of like a software patch for the nodes in a cluster. In this case though, the nodes seem to be resistant to patching, even if they might desire it...like there's some sort of other software (or something) preventing it.
