Kate has a few helpful suggestions for anyone who is thinking about coming out as an atheist:
Step Six: Remember that you’re not alone. Participating in meet-up groups and forums will help you feel like you’re a part of something, especially if you live in an area of the world where being an atheist is particularly bad for your social status. And if all else fails, come out to me. I’ll accept you.
Her advice is helpful.
Not that Kate says otherwise, but I would actually suggest not telling your family (if you think they’d have a problem with it) until you’re out of the house. Wait till college if needed. No need for the extra drama.
Whatever you do, don’t keep it to yourself forever. By coming out as an atheist to people you know and trust, you’ll give them an opening to come out, too.
No doubt there are people around you right now who are afraid to say they, too, are atheists.
By letting them know you’ve gotten over religion, you’ll be doing them a favor as well.
