Could atheist westerners, please explain?

I don't think he even knows what secularism is. He seems to be living in a fantasy world comprised of religious dogma, mythology and awful propaganda. One of us two is hopelessly deluded. Maybe it's me, I don't know.

I really have tried to have a sensible conversation but I feel like the answers are so random and not even internally consistent that it's going in pointless circles. I can only assume he has never been to a secular country, or if he has, his institutionalised outlook finds it unsatisfactory.
