My late partner’s mother encouraged her to question everything. The family was Iranian and moslem and she was the only girl with four brothers. From the time she could reason she thought religion was silly. I came from a family of 7 kids. We were raised Catholic but it was never pushed on us. I was in my 40’s before a pivotal event caused me to leave religion. All but one sibling became atheist at different times for different reasons.

I was born and raised in a very catholic family.
Indoctrination didn't take.
I remember sitting in church, listening to the priest's bible readings and sermon.
Even as a young child, I knew what he was saying made ZERO sense to me.
Even before I knew what an atheist was, I knew I didn't believe.

I lost my religion when I had kids. It didn’t make any sense to me that you would even entertain the ideas of your children to be tortured horribly for the rest of their lives if they didn’t obey me. It also made no sense that I would destroy them because they were homosexual. I’d still love them regardless

I came to be an atheist when they told me sex had to be sanctioned by god and the church!?! I was like,”Fuck that shit.....”

I think your summation is more correct. I raised my kids atheist, and one decided her teen rebellion was to join the Faith Apostolic cult (Jim Jones' reorganized cult). Unfortunately, she's still drowning in koolaid.

If Santa Claus is a myth then so is Jesus.

I was born in pretty much an atheistic family, My grandfather was an atheist, my dad was an atheist and my mom well, she really just taught us to believe in god and to know the difference between right and wrong.
She hated religion and figure we would find out about it when we got older and then we would have to learn to deal with it.
So, when it comes to god or gods, that is man-made and put into books, I am an atheist, but when it comes to whether or not there is a real god, I don't know, therefore I am agnostic.
I figure that if there is a god and it wanted us to know about it, it would present itself in a way that no one can dispute. So, until such a time occurs I'll just sit here on the top of my fence. I don't waste a lot of time thinking about it.

I do not believe that some people are born atheists, per se. I do believe that genetic effects leave some people more analytical and truth-seeking in their intellectual development. That would increase their tendency toward atheism.

You are correct. I was born into a Mormon family, and was raised to be a Moron (oops, Mormon). As a child, I had some doubts, but I stayed in the church for the sake of my parents, who would have been very disappointed if I left their church. In my late teens, I started doing personal research, and I discovered that Joseph Smith was a false prophet, because he wrote "revelations" and "prophecies" that failed to come true. I knew Moronism was false, but I waited until I moved out of my parents' home to abandon Moronism, so as not to disappoint my parents. My scientific study of the prophecies showed me that Mormonism was a scam. Now, I am very glad to be free of that scam. After leaving the Moron church, I applied science to the Bible, and discovered that the rest of Christianity is a scam, too.
