I see that in both esoteric and exoteric study of all ideologies.
Ideally there should be a unbroken line of continuity within any great Faith system between its exoteric and esoteric expressions. Sadly, for many reasons, such is not the case and expressions arise that could be called "fundamentalist", so called "only ways", that draw in the fearful and faithless - and it seems these expressions capture the headlines and provide the platform for those such as Richard Dawkins to deride "religion" in general.
While personally I regret that more people do not recognise the great repository of wisdom held within the great Faiths of the world, I am also able to recognise the "natural healing power of temporality and spaciality" that arises in so many secular ways that are not an explicit part of any faith. From "On The Road", "Black Elk Speaks" to "Finnegans Wake", from a mother's love for her child to any other spontaneous act of empathy and compassion; if a Christian, these can all be recognised as "the salvific work of Christ", the Living Word which should - but alas often does not - follow from the Word as Text.
"I bring fullness and satisfaction to the world,
like rain that spreads its moisture everywhere.
Eminent and lowly, superior and inferior,
observers of precepts, violators of precepts,
those fully endowed with proper demeanor,
those not fully endowed,
those of correct views, of erroneous views,
of keen capacity, of dull capacity -
I cause the Dharma rain to rain on all equally,
never lax or neglectful.
When all the various living beings
hear my Law,
they receive it according to their power,
dwelling in their different environments.....
..The Law of the Buddhas
is constantly of a single flavour,
causing the many worlds
to attain full satisfaction everywhere;
by practicing gradually and stage by stage,
all beings can gain the fruits of the way"
(Parable of the Dharma Rain, from The Lotus Sutra of Mahayana Buddhism)
