Blame it on my parents. They always told me to "think for myself". I doubt they ever considered what would happen if I really did that.
Now, I suspect what they meant was, "Think what we tell you but do it in your own words." Too late. When I was 13, I began to question everything and soon the total absurdity of religion became apparent.
Because I have been “encouraged” (forced) to read the bible many times, it was easy for me to see the contradictions in the book, what christians professed to believe, and how they lived.
When I refused to go with them to their church, they said they “Would make me go."
I asked them, “How are you going to make me? How will forcing me to attend church change my mind?” Already, their attitude was starting to harden me against everything else they would tell me.
Their next idea was to have their minister talk to me. I told them it was a waste of everyone's time. They persisted and had him come to the house to “Talk some sense into me.” (as if they ever works for anyone) After about 15 minutes, of him quoting the bible to me and me pointing out that he was either wrong in his quotes or showing him how it said something else in another place, he became very angry and told me I was going to hell. I suspect it was because I knew the bible better than he did and was, at age 13, able to prove how ridiculous his arguments were.
I told him, “If there is a Hell I'll see you there. Save me a nice place, OK?" He said I was an impertinent, disrespectful child. By then, I was angry myself and for the first time, I told a christian that he was a hypocrite, a liar, and a fool. My parents insisted that I apologize. I refused and left the room to a lot of yelling and threats.
For the next four years, I heard about this at least once a week. So the night I graduated high school, I left my parent's home and didn't see them again for well over a year. By then, I had completed a couple of years of college, which fortunately, I was able to pay for myself. I was entering the army and wanted to try to make peace with them, but had to listen to the same old recriminations and arguments again.
The next time I saw them was two years later when I was getting married. After several years of an on-again, off-again relationship they finally agreed to just not discuss it any more. I'd like to say that worked, but slowly subtle hints became outright condemnation. Then I took a job transfer from Ohio to Arizona, so family meetings were rare enough to become occasions for something other than contention.
What did I learn? Even your family can turn against you if you refuse to share in their illusions.
