Teaching your child something or encouraging them down a particular path is normal and pretty much unavoidable. Nor, to be honest, do I see much benefit in attempting to avoid doing so.
The problem is the equation of any sort of religious teaching with "indoctrination" and "brainwashing". Those words are meant to imply something above and beyond normal behavior.
I'm reading a novel called "The Violent Bear it Away" about an infant that was kidnapped by a crazy great-uncle who believed that he was a prophet of God, and that he needed to raise up a boy to take his place as prophet. This child was raised in complete isolation, being taught only the great-uncle's version of events, form of religious conviction, and method of viewing the world. This child was brainwashed, truly indoctrinated.
Now, you guys are all perfectly free to water down the term, and utilize it for the average family that takes their kid to church and has them pray before going to bed, but you shouldn't expect everyone to agree with your agenda-laden redefinition.
As for me, I'll continue to reserve the terms "brainwashing" and "indoctrination" for cases that truly call for it-- for exceptional occurrences, and not normal child-rearing.
