I'm not sure I see how. If your opinions are not guided slavish adherence to an ideology, I shouldn't be able to guess what you'll say about a story just by reading the headline and noting what major ideological groups it's likely to piss off.

Predictable does not imply partisan (though partisan likely does imply predictable).

By way of example, I predict that all of us will say that rape is wrong. Which ideology is that "slavish adherence" to?
