Coming out to my family was an accident. I was content with just ignoring my mother when she would ask each time I moved whether I had found a good church to go to.
I have a blog,
http://bjornisageek.blogspot.com, for anyone who cares, and on this blog, I was tinkering around with having a web cam on it. I signed up on a site called StickAm which would put a module on my blog which would stream my web cam. I used it to see what my cats were up to while I was at work. The answer was, nothing, they just slept in different places in my apartment during the day. Anyway, my parents read my blog, and my mom clicked on the StickAm module, which led her to my StickAm profile. In my profile, I listed my religion as Atheist.
Once my mom found out, she called me while I was driving home from work, crying, she went on and on about how she's disappointed in me, how she didn't raise me this way, how my soul was in danger, and how much she wanted to see me in heaven. I tried to figure out what the big deal was. She knew I didn't go to church, and she knew I volunteer all over the place and I'm a good person. But, now, since I was an atheist, that doesn't matter. Her conversation sounded a lot like a parent upset with their kid coming out as gay, "but I didn't raise you this way, but you dated girls in high school, I'm disappointed in you." In place of "you dated girls in high school," my mother said, "but you went to confirmation." She mentioned something about not letting my father know. He's going to Luther to be a pastor.
After then, my mother wouldn't speak to me. She'd send me emails once a month with short questions which had nothing to do with me being an atheist. She told my grandmother in New Jersey who was married to a minister, and she felt it was her duty to explain how upset she was with me, and disappointed. She wondered how anyone could go through their day without talking with Jesus. I knew my family was religious, but this was getting nuts. My mom still wouldn't talk to me, until the 35W bridge fell. She thought I died, so she called frantically to make sure I was alright. Then she would talk to me again.
Since then, I've had a secular wedding, and my extended family knows we are atheists. No one had a dust up over it, but I'm sure it made for interesting conversation behind our backs, as it's my family's way.
