It's both. Indoctrination is a complex bitch. I grew up (quite) religious and was definitely "happier" in some sense when I could just easily dismiss every real, major problem/injustice in life with some glib, simplistic talking point or Bible verse. To say nothing of the confidence and self-assuredness that goes along with "knowing the truth" and being on the "good side/team," not like those wordly sinners over there.

It IS much easier and comfortable that way. Deep down, I was utterly miserable, but it took a long time to understand that and see through it all.
