But I've also understood that the question of "Atheism" vs. "Religion" is something hugely different in the US compared to, e.g, northern Europe. Being an atheist in the US is apparently a big deal, something that people care about. Around here it's instead like, say, owning a grey-blue jacket. It's not something you think about very much, it's certainly not something you go preaching about, but if someone asks you will know what to answer.
