In general, political opinions tend to fall into the “sacred cow” category. People tend to identify with their political tribe and want to believe that their tribe is virtuous and smart, while the other tribe is mostly made of lying idiots. Of course, these dichotomies occur on a spectrum. You can have a little bit of an emotional attachment to a belief, or it can be fundamental to your worldview and identity. You can be a little tribal in your political views, or hyperpartisan.
