When you (not personally you, every one of us) see such a discrepancy, we have a choice: either label the person who displays it as "stupid" or "lying", or question our assumptions about their beliefs or actions.

In particular, a lot of people who align themselves with libertarianism quite commonly have their views simplified to an absurd extent. If a person advocates for "free speech", do you necessarily think that they advocate for everyone being able to publish anything at all, without any repercussions whatsoever? If a person says "capitalism rules", do you honestly think that he believes that no company should be regulated in any way?

I think that at the point where you simplify a person's political views to two-word formulas, you may have already lost most of the knowledge of what they actually believe in.
