My mom was a lapsed Atheist and my dad was a lapsed something I presume. I never went to church, except for weddings, scouting, and to make grandma happy.
I remember when I was 6 in KEYS, afterschool/beforeschool program, I told the boss lady I didn't believe in God. Boy did that cause a shit storm. But the majority of my friends were atheists as well, many were like reform jews or something technically but were really atheists.
