In my household growing up, I really had it impressed upon me that religion is baaaaad. My father called it fantasy and fairy tales. I remember that my sister moved to Utah and she converted to Mormonism. She was afraid to tell him and she hid it for a long time. If I wanted to do a church activity or any religious activity, I had to do it on the sly.
When I was an older teen my father chilled out a little bit, and he said that I could do whatever I felt was right. But it's been my personal experience that when you grow up with these extremes, one way or the other, it's not ideal. My father was a physician and in my opinion, he worshiped science as much as any religious extremist worships an object of faith. And he was sort of noisy about it.
