The issue with having complex views is that minority opinion doesn't really matter in a democracy. So people gravitate towards one of two largest pieces of the pie and tie their beliefs in to match that pie.

Even if someone subscribes to say "85%" of "most liberal beliefs and ideologies" they're still a liberal/Democrat and will be held to believe 100% of the "commonplace beliefs".

This is why all Republicans are blanket-washed as religious nutcase, global warming denying bigots. While all the Liberals are caricatures of 1984's Thought Police.
