Maybe a possibility, but I am not sure at all.

To arrive at a scholarly apposite rendition, it well-behoves one to ascertain if these adjectival qualifiers are sought to describe A Person's idea or in fact the Person himself/herself. Perhaps they are to characterize, albeit disapprovingly, a School of Thought, Government, Social Strata, Culture, Institutionalized Movement, Perverted & Corrupt Revolutionary Ideology, Religious-based Vigilantism,...etc., in which case a fitting rendering may be then duly achieved by examining the context, depending on the audience and occasion.

The above notwithstanding, if I may conjecturally presume that The Asker is seeking equivalents for a description of a given Social Class representing a specific politiaclly-motivated, dogmatic, parochial, illiberal and bigoted system of belief / thought-school which is self-righteously oblivious of its era & milieu, then I may be able to have a few suggestions below :

- Ossified & Dogmatic system of ideation
- Obdurate & Over-zealous ( religious ) individual
- Obscurantist & Bigoted religious sect

It goes without saying that a more refined reasearch for improved rendition can be arranged by examining the context, if available.

After posting the above, I re-read the actual question and now understand the context per the sentence given, to refer to an individuals fanatic attitude & narrow-minded behaviour, in which case, two of the above suggestion(s) may still be of some use.
