To me, it’s the word that best describes political parties (all of them, thank you very much).  If we could dispose of platforms and party needs and all that unnecessary hoopla, I bet we could get a lot more done once people had to stand on their own two feet and make their own decisions.

[From Spanish los intransigentes meaning “the uncompromising ones” and the name of an extreme political party, from Spanish transigir meaning “to compromise,” from Latin transigere meaning “to come to an agreement.”]

Usage: It is impossible to serve the will of the people when holding an intransigent position.
