Here is the great German polymath-historian Oswald Spengler on how our Western (what he termed "Faustian") culture is inherently dogmatic and intellectually-intolerant; due to what he attributed as a "space-invasive" dynamic that ties in with the West's perception of space as being infinite. Spengler compares and contrast's the Western version of piety to that of the Greco-Roman "Classical Culture" of antiquity. From his magnum opus, Decline of the West (with my own emphasis highlights added):
We see this same pattern pop up time and time again with various Western religions and ideologies; whether it's Christian fundamentalism or (as we're now seeing today) progressive liberalism, we see the same rigid dogma-adherence and shrill denouncement of anyone who refuses to toe the line. Even with so-called "free thinkers," it's more like "you must free-think the way I free-think!"
What we moderns have called "Toleration" in the Classical world is an expression of the contrary of atheism. Plurality of numina and cults is inherent in the conception of Classical religion, and it was not toleration but the self evident expression of antique piety that allowed validity to them all. Conversely, anyone who demanded exceptions showed himself ipso facto as godless. Christians and Jews counted, and necessarily counted, as atheists in the eyes of anyone whose world-picture was an aggregate of individual bodies; and when in Imperial times they ceased to be regarded in this light, the old Classical god-feeling had itself come to an end. On the other hand, respect for the form of the local cult whatever this might be, for images of the gods, for sacrifices and festivals was always expected, and anyone who mocked or profaned them very soon learned the limits of Classical toleration - witness the scandal of the Mutilation of the Hermae at Athens and trials for the desecration of the Eleusinian mysteries, that is, impious travestying of the sensuous element. But to the Faustian soul (again we see opposition of space and body, of conquest and acceptance of presence) dogma and not visible ritual constitutes the essence. What is regarded as godless is opposition to doctrine. Here begins the spatial-spiritual conception of heresy. A Faustian religion by its very nature cannot allow any freedom of conscience; it would be in contradiction with its space-invasive dynamic. Even free thinking itself is no exception to the rule. After the stake, the guillotine; after the burning of the books, their suppression; after the power of the pulpit, the power of the Press. Amongst us, there is no faith without leanings to an Inquisition of some sort. Expressed in appropriate electrodynamic imagery, the field of force of a conviction adjusts all the minds within it according to its own intensity. Failure to do so means absence of conviction - in ecclesiastical language, ungodliness. For the Apollinian soul, on the contrary, it was contempt of the cult, ασέβεια in the literal sense, that was ungodly, and here its religion admitted no freedom of attittlde. In both cases there was a line drawn between the toleration demanded by the god-feeling and that forbidden by it.
