Well not true in my family.In my own experience atheists are either (1) severely traumatized and they blame God for it or the opposite extreme (2) born with sterling silver spoons in their mouths.
I've also noticed that a lot of them had a bad relationship with their father. Often, our relationship with our father has a lot to do with how we think about God and faith.
My father was an azzhole and I simply tried to be the opposite of him.
My mom was also a sh!t and my elder sister tried to be the opposite of her.
Our baby sister, the youngest, is a sh!t just like our mother was however.
Our mother was very superstitious however and at least took us to church so that we could become brainwashed Catholics.
Whereas I have become a recovered Catholic and my mind is now free, I still strongly believe in God however mostly for Philosophical reasons (San Tomas Aquinas, Rene Descartes, etc.).
