1. An ideologue is only interested in their own view of the world to the exclusion of fresh ideas or counter arguments.
2. An ideologue is never satisfied with the personal opinions of others because they want to convert others to their own opinions
3. An ideologue cannot compromise because everything is black and white. If you continue to disagree they must label you as an enemy. In fact,
one clear sign you are dealing with ideologues is their tendency to smear with labels those who disagree with them.
4. The ideologue has no interest in the free exchange of ideas. They prefer to lecture with rehearsed persuasions reciting memorized arguments.
5. Ideologues prefer their own source material which they present as material fact rather than opinionated bias. Excluding other people's source material is their chief strategy in disallowing counter-factual disproofs of their world view.
