I'm not sure I fully understand the question so this may be non sequitur...
If you are born into an advanced civilisation where thousands of individuals have already done all the thinking and actions required to build said civilisation, you cannot hope to start from first principles and work it all out for yourself, by the power if reasoning.
It is far easier to go to school, listen and learn and regurgitate the 'right' responses to exam questions IF you want to get on in the outside world. You have to accept the ideas (aka ideology) handed out to you.
Thinking for yourself will only cause you to be treated as a heretic.
So, reason can, on occasion, make itself an enemy of ideology. Whether that is reciprocated 100% of the time or only on those same occasions, I cannot say. The inquisition travelled around in search of heresy. "Seek and ye shall find", as the saying goes.
Would anyone like any toast?
