Hair-splitting circular firing squad.
Inflated with a deluded sense of enlightenment (aka narcissism), lacking a sense of proportion nor any intention of being practical and/or flexible, one cannot get their priorities straight, end up dying on some trivial hill skirmish among themselves, even as a savage, true threat marches into town virtually unopposed, goose-stepping all over main street.

EDIT: Reminds me of that Monty Python scene in “Life Of Brian”, The Peoples’ Front Of Judea, not to be confused with The Judean Peoples’ Front, not to be confused with The Judean Popular Peoples’ Front, etc.
