Conservatives tend to emphasize loyalty, authority, and purity as fundamental values, over and above the more widely-shared values of care, fairness, and liberty.[0] These "binding" values are a foundation for in-group vs. out-group thinking. And because loyalty and authority compete with fairness (and win out over it) there is less of a priority on the law as treating everyone equally.
