Hmm, anything really, school, video games, movies, ideas, TV shows, philosophy/religion, whatever is happening then and there, etc.
I mean, like, specifically when philosophy and religion comes up. See, the truth is, atheism is a simply a single type of belief amongst a rejection of all other supernatural beliefs. I'm going to assume that you don't believe in astrology, either. But if your friends did believe in it, I doubt you'd feel any sort of pressure to take up for "non-astrology." I've grown to feel the same way about atheism. There's no point in lying about it, but short of being asked a direct question, I don't think there's any need to "represent" for unbelief either. To be sure, there are times when the stakes are real, and you'll have to step up and destroy a bad argument when you hear one, but it sounds like this is a question of simple chit-chat among friends.
It sounds to me like your instincts are good enough that it's unlikely you'll offend anyone in the course of basic conversation about your unbelief. Unless of course, you're in conversation with people who are simply determined to be offended (and there are those people). Nothing you can do there. For some people, belief in God strikes at the core of who they think they are, and unbelief will necessarily be viewed as a de facto attack on that assumption.
Richard Dawkins admits to publicly saying grace when it's his turn to lead the prayer at Oxford dinner. He does so out of respect for the long history and tradition of the ritual. He also quotes the philosopher A.J. Ayer who once said, "I will not utter falsehoods. But I have no objection to making meaningless statements." Point being, there's no medal for jumping at every opportunity to shoot down superstition. For every conversation, its proper time and place.
Just so you're aware, Atheism is a prohibited topic in this specific forum, so this thread might be getting locked soon. Feel free to PM me if you want to continue further, or maybe you can re-post in the Non-Catholic Religions forum.
