Unacceptable reasons not to date someone

You just found one!

You’re married to the person. It’s really unacceptable that you’d be unwilling to go on a date with them.

Indeed. If someone won’t date outside of their race for racist reasons, it’s the racism that’s the problem, not the failure to miscegenate. The potential date is dodging a bullet.

Huh?

I was just using myself as an example, it had nothing to do with me in particular. It could have been anything.

I’m not here to deny your first hand experience. Let me offer my first hand experience as a contrast.

I am a hard core “It’s all poppycock, pure and simple” atheist. My wife is a learned theologian and for some time was working on Episcopal ordination. Which fell apart for essentially political reasons in the church hierarchy.

We have been married 28 years & had a close relationship for 5 years before that.

She has yet to do what you describe. We have yet to have an argument on any topic, much less a religious topic. She is my perfect mate and she says the same of me (poor benighted woman :)).

It requires two intelligent people with mature attitudes and confident natures. But it absolutely can be done, and done effortlessly.
IMO, your problem was not that your ex-wife was religious. It was that she was an idiot and a stubborn person. Religion was merely the excuse or framework she used to justify her idiotic stubbornness.

Note my original response to edwardcoast was not that any/all religious differences are immaterial. It was that some religious differences are not insurmountable. And in the numbers game of online dating, that’s probably not the best filter to apply early. It’s also an easy one to apply (with far more specificity) in person on the first date.

As with all things involving humans, YMMV.

In my first marriage, I was a Catholic married to an atheist. It was perfectly fine. My religious beliefs slipped away during the marriage, but certainly not because we ever argued about or really talked about religion at all.
