The religious aspect of the relationship becomes more of an issue as the relationship becomes more serious. In a lot of my experiences, the religious person thinks that I will convert at some point and believes converting it is a true testament of the love for them which is far from the truth. That's when the relationship ends.

I have been through so many relationships with christian women, going down to the road to marriage, and then after two years, it becomes, "I would marry you if only you were a christian." I am done with christian women, all of them.

I personally don't mind as long as there is mutual respect for each others beliefs.
I come from an Indian background and culture and religion has a massive overlap. There is also a lot of superstition and pseudoscience within the culture which I'm very skeptical about. The problem I have is that I would find it difficult to abandon both the culture and the religion.
Ideally I would like to date someone that is from a similar background culturally but not so deeply rooted in the religion.

Not even at gun point.

Santa. The Easter Bunny. The Tooth Fairy. Jesus. Heaven. Hell. They're all the same... stories told to children to frighten them into submission.

Anyone who believes any of them are real is not working from a place of rational thought. I prefer intelligent conversation from my prospective mates.

I've tried it never works out.

I wouldn't rule out dating a believer, as long as each of us respects the other's journey and boundaries.

Was married to one for 28 years. She was culturaly Christian and not pushy about it, so the only thing I asked was let's not decorate with angels and Jesus and you go/take the kids if you want to. She rarely did.

If that kind of arrangement did not work for a date, then that would be the determining factor.

Yes, and I have done. They would have to show as much respect for my atheism as I would for their faith, though, and any attempt to convert me would be an immediate deal-breaker.
