I grew up in a somewhat religious household - my father would be waiting at the Church of Christ doors 3 times a week for them to unlock so he could go get his dose of religion. 

When I was in elementary school, my parents were divorced, and I saw how the church treated my mom, who was already somewhat of an outcast, having been divorced once before marrying my father, and how some other members of the church did 'favors' for my father that weren't quite legal (one was someone who worked at the local bank, combined accounts that my father's name wasn't on).  

After seeing that, seeing how other members of the church acted outside of those pews, and realizing that some of those stories I was taught in Sunday School were just too far-fetched, I began to search for the logical truth.

My search did include what I knew of other religions, and I boiled that down to "help others", and stuck with what science could show as facts.

My parents are still very religious - my stepdad is a Deacon, and my mom tries to preach to me whenever she can, but this is just a part of my life that's not the same as my parents, and I accept that.
