If someone doesn’t think about politics then they shouldn’t be on the chart at all.

Disagree.

The lack of a strong position is a positon in itself. Many polticians, many governments, lack strong positions on a multitude of issues. If a lack of concern isn't on the chart, the chart is missing something important.

Are you free because the government cares about protecting your freedom (ie: USA), or are you free because the government doesn't care to restrict it (ie: UK)? There is a massive difference.
