I would just tell them you hate god.
Since I was a child, I didn't care about god. Yeah my parents were religious but I was never one bit curious.I don't care if god does or doesn't exist at this point.At one point I was agnostic. Now I am Nihilistic.
i don't hate God, I believe in a multidimensional being that watches over us. Wether his name is God or not, i could care less. I like to go to church becuase it connects us as humans to someone from a different dimensionI care about God because i find it good to have a connection to someone not in this realm
even if you don't believe in God, being apart of a church is a good thing because you have a small community backing you. you can stop going when you move out.
