Ideology is something that all aware people share.
Some ideology is founded on principles that are rooted in dogmatic group think; such as religion and politics.
Both are the only real basis for which we humans interact and relate with one another, they are the heart of the human condition; coupled with the advent of conscience and the ability to craft weapons as objects of worship that enables the masters the power that is used to reign over their subservient subjects is the catalyst to which gives ideology its influence.
For those whom do not find their selves subject to any ideology either by choice or circumstances not of their own making; they are either lost or enlightened; to what extent and to what degree is all in the eye of the beholder.
Every human strives to find their niche and their place at the table of their masters; the way and means to which we get a seat at the table is the determining factor of how much humiliation we are willing to subject ourselves to fill that seat.
In the case of religion, some practices simply open their doors to those who seek the wisdom and guidance of the tenets of faith that their sect provides; others will demand you spill the blood of non-believers who do not subjugate themselves to the dogma of their sect. In either case, both require participation that requires little or no individual awareness; loyalty is paramount to the success of religion, and to achieve that loyalty, one must relinquish their ability to reason.
All in all, you're just another brick in the wall...
