Here in the States, you don't meet many people who are politically agnostic. The closest we get is maybe people who declare themselves to be independents because they have a unique worldview or simply because they dislike both dominant parties.
What's important is to pay attention to whether our affiliations impact our ability to listen. In the more extreme cases, strong affiliation disables listening. We have little patience for what we deem "wrong."
I don't think I'm alone in arguing that a country where people cannot listen well to each other around political questions is a country divided. And a country divided is a country at risk and less than a full contributing member to the wellbeing of the world.
