Why are you not a Christian?

I was raised a Christian and for a short time I prayed, lived my life under the assumption of pleasing this God, and didn't like those who attacked Him. But, I eventually realized that nothing, besides the household that I was raised in, lead me to this God and living my life around the codes/rules. I thought this was quite sad. I didn't want to be some sheep who can't think for himself and have my whole life formed around something that I only accepted blindly because of the conditions I grew up in.

Now, I am no longer a Christian. I still haven't figured things out for myself yet, but I do know I don't want to be associated with organized religion.
