My sin is not always coming out and telling people I'm an Atheist. Occasionally going to church for the social interaction for my daughter, etc. After all, they say any religious person that's happier than a non religious person is happy because they have friends at church and for no other reason.
I especially like the "Carol of the Bells".
Just joined, first post.
My grave, Atheist sin... I have my girls enrolled in a Lutheran pre-school. I confess, it was convenient, and its only one year - I survived 20+ years of Catholicism and escaped to this garden of rational freedom... so one year wont hurt. Though I was pretty concerned in their first week, they had learned that god created everything!... and then relieved when that was followed by, "its ok daddy, we know that you and mommy created us, your like our god!"
My more delicious sin, is that I looked forward to volunteering to help drive the Lutheran "school bus" on a class field trip! (Mission accomplished). I am enjoying my decietful undercover atheism gaining high favor and appreciation from the school.
Oh, and I do enjoy christmas and singing christmas songs... which reminds me one further plus with the Lutheran school... the wife and grandparents (on one side) got to enjoy the kids first and likely last christmas program at school!
I held hands with my friends as someone said "grace" before a Thanksgiving dinner.
B-but I didn't say "Amen," so I'm still part of the atheist club, right?
Once in a while I pay 10$ to go see exorcism/ghosts/werewolves/superheroes at the movies :(
But I'll confess, every year they become less and less funny.
I used to exclaim 'Christ in a handbasket' constantly, although that was less a religious statement than just a quote from Bill in Left 4 Dead. I have since switched to 'By the hammer of Thor!' or 'By Odin's beard!' to confuse theists. I should begin using FSM references as well.
Sometimes I say 'damn' but never 'god damn'.
On the other hand, if someone sneezes, I say nothing, or occasionally 'May probability adhering to a scientifically predictable cycle prevent your natural selection by disease' if I can get it in quickly enough.
