Christianity almost impossible without indoctrination

[Esquilax]

Everyone has had some influence from someone at some point in their life that was instructive in forming their view on whatever subject. It doesn't mean everything you believe has to be programmed into you like a machine but only atheists believe this if they deny any basis for freewill. You can see the madness involved there if you claim indoctrination for others when that's the only basis for what anyone ever believes including yourself seeing as you're biological programmable machine like everyone else.

So we can add another thing to the list of things you've seen fit to talk about without knowing what they are: indoctrination.

Indoctrination isn't just the act of being taught something during your formative years, Sword. Indoctrination is being taught that thing in such a way that discourages further investigation or contradiction of that concept; like, say, being threatened with burning in hell if you don't believe that thing to be true. Among other things.
