Precisely. I was raised in an atheist household, and was never exposed to any religious indoctrination, our community was very sparsely populated and made up of people in the same organisation my father worked for. Not at all religious, although our home was located in an anglican christian diocese.
It's easy for me to sit outside the box of experience of religious study and church etc.. and judge.
We did not celebrate easter or christmas. No baptisms, no sunday school, none of all that!
I studied Asterix and Obelisk and Tintin comics or played with my computers, on sundays.
I learned more about christianity when I went to comprehensive school, in my RE classes and meeting kids from religious backgrounds.
