Everyone needs a framework to orient themselves in life. The difference being that, people with a higher degree of trait Openness (let's lump the "Leftists" along with them, whatever) are more driven to explore different possibilities of what their life might look like.

And they often feel threatened by the prejudice that less open people often harbor for people exhibiting behaviors that deviate from the norm.

This is an experience of threat that's less talked about, as opposed to the threat by the "other" that conservative people experience.
