Atheists in church

[Spongebob]

I know quite a lot about principles. It's not like I've ever done anything immoral, unless you count having premarital sex a few times, with the same girl, or smoking cigarettes, but I don't consider those things "immoral", although I will admit the sex is pushing it. My (potential) immorality has more to do with what I would do if given a significant amount of power, and what goes through my head when I think of that.

You certainly know how to pretend to have principles.  But you don't know how to have them.  If you talk about of both sides of your mouth, you don't have principles.  That's kind of how it works.

I'm curious; you say you aren't Christian, so why is premarital sex immoral?

Are you Zoroastrian or do you just think your username sounds cool?

Church is not the right place for an atheist. That's like going to a concert, but you don't like any of the bands that are playing.

Sorry, but that's not for you to decide.  And that analogy is no better than the chess one.  In fact it's quite the same.  Church is far more complex and includes non-religious cultural aspects and community.
