The reason that conservatives tend to understand liberalism to a degree that liberals do not understand conservatism at the present moment isn’t about conservatives being smarter or more worldly; it’s because we live in a liberal society, so everybody understand liberalism. Liberalism is what’s taught in schools, it’s the morality in the background in TV and movies, it’s the worldview of most famous people, and so on.
We’ve all just been exposed to liberals and to liberalism to a degree that liberals have not been exposed to conservatives and conservatism.
