Christians frame things as "All of the Christians are sitting here in one group, and all of the non-Christians are sitting over there in a different group."

And that's fine. It's absolutely true.

And if God exists and is the creator of the universe, that's pretty good for the Christians, and pretty bad for everyone else.

But if God doesn't exist, then the Christians are just all together in a group that isn't getting to enjoy their existence while the rest of the world is just trying to enjoy theirs, and the Christians are just trying to prevent those other people from enjoying their lives.

Either way, I'm surprised that the creator of the universe would organize things so that it would look that way from the outside.
