It may have an objective definition but I don't think I've ever heard it used in a way that didn't have a connotation like this from chc:
"The negative connotation of that word is the implication that you are bound and determined to defend some position and will not be moved — stemming from its roots of defending literal dogma. People take it to mean a sort of closed-minded, blind tribalism."
