By ideology I mean a set of ideas, religious or secular, to which an individual subscribes blindly regardless of the objective and testable truth of  the ideology or of any contradictions which it may contain.

For the true disciple  of an ideology it must be accepted in its entirety or not at all. The reality of all  ideologies is that they are incomplete descriptions of  the world at best and plain wrong at worst. Religious ideologies are either  ragbags of unsupported imperatives, for example, Christianity and  Islam, or, as is the case of Buddhism, a system of thought which has a specious appearance of rationality but which, even in its purest  form, is just as irrational because its logical arguments derive from unsupported  assertions such as the behaviour expected of those who are to  reach nirvana, a state as mythical as Heaven or Paradise.
