My parents are both orthodox Jews. Following in their footsteps and subscribing to every rule of their religion was never a choice, it was expected. As a kid, it was all I knew. Keeping kosher was just one of the many aspects of my daily life and I only ever hung out with other Jewish kids so it's not like I noticed a difference anyway.
But as I got older, my views started to change. The more that I was freed from my parents restrictive views, the more I started to develop my own belief system. In high school I learned about Darwin, evolution and developed a passion for science. All of a sudden some of the stories from my childhood just seemed foolish to me. It wasn't that I didn't respect my parents beliefs, I did, they just weren't for me. It's just that my progression to considering myself an agnostic was liberating and most of all, natural.
Unfortunately, my parents didn't feel as comfortable with my new beliefs as I did. At first it was just 'a phase' then as my thoughts persisted past a few months, they started to grow concerned. They blamed me, they blamed themselves and made it seem like my decision to have my own views on the world were a terrible mistake.
It has been a few years since I've moved away from Judaism and my parents have slowly begun to accept it. Going away to college helped as me being independent from my parents seemed more OK to them. While I'm happy with the place we are at now, it was a real struggle filled with screaming matches and tears. But I feel better now knowing that I had the power to make my own decisions in life and I think my parents have come to respect my beliefs, even if they don't agree with them.
