You've answered your own question.

You said it brain washed from birth

Yes, I'm a perfect example. I never believed it. There's not one Catholic molecule in my body. Not a drop of residue. I thought it was crap when I was just a kid. My opinion has only intensified since then.

I think you can only avoid the brainwashing by reading widely. This is not (I understand) encouraged in fundamentalist families.

I actually was kind of brainwashed when I was a kid. I believed god existed and I believed everything my teachers taught me. My atheism more came about through convenience of not wanting the same stuff shoved down my throat all the time. It wasn’t until later when I learned to look at religious teachings with a critical eye that I realized that an option for “nothing” existed.

Tell us about your brainwashed experience.

Brainwashed to a human is simply water to a fish... we deal with the life we know/understand.

Nobody sits you down and says "These are all the religions. Take your pick." You just do what your parents do, and so that's all you know for quite a while. Most people want to fit in with their "tribe", and it takes a while to break away from that.

Of course! Most atheists I know were brought up religious and then de-converted. We are apostates.

I don't think it is possible NOT to be brainwashed and indoctrinated in a religious family. It is possible to NOT have the indoctrination take hold and rule your life

It doesn't matter, current conditions make the awakeining inevitable. Its just a matter of time
