I’d have thought it’d be on a case by case basis.
As I said my husband is actually a minister and is the most amazing and selfless man I’ve ever met. I can’t imagine writing off dating him based purely on his beliefs.
Maybe I just got lucky and found a wonderful man who happens to believe deeply. Are they a rare breed?
The thing is, for me, dating someone based on their beliefs, or lack thereof, makes sense. It is a core part of who they are. I don't have a belief in a god or gods. It's how my mind is wired. Long experience has taught me that I'm not compatible with anyone who is religious. To me, it's a fundamentally different world view.
I wouldn't extrapolate from that that atheists/ agnostics cannot successfully have relationships with religious people. Clearly they can. But I can't and can therefore understand why someone else might want to rule out anyone religious.
It's great that you've found someone you're so happy with and it's great that (presumably) you have enough core values in common. For some of us it just doesn't work that way.
I think it is fairly common on Mumsnet to think that anyone who has a religious faith is an extremist
Certainly I don't think all religious people are extremist. But they do all believe that there is some sort of mysterious higher power that governs the universe and explains its mysteries. This just goes fundamentally against my values.
