noun

  1. a person who zealously advocates an ideology.


Etymology

Origin of ideologue

1805–15; < French idéologue; see ideo-, -logue


Explanation

An ideologue is someone who has very strong beliefs or opinions and stubbornly sticks to them no matter what. An ideologue will insist they're right even when evidence suggests they might be wrong. If you call someone an ideologue, it's an insult. You're not just saying they believe in something, but that their belief is unreasonable and unbending. An ideologue can't have a thoughtful discussion about a topic, and they aren’t able to consider other perspectives. Ideologue derives from the Greek idea, "form," and logos, "word or speech."
