x I don't really follow any religion so I guess I wouldn't care too much. I'd at least give dating a try.
Marriage would depend on how much it would affect my own lifestyle (if they made me go to church or participate certain practices, etc.)
I'd prefer to date someone who's more lax about their religious views if they have any. Like someone who is Catholic but doesn't bother going to church for example.
No, you've been mistaken about what an agnostic is. There's agnostic theism and agnostic atheism. Unless you know with certainty that your god exists and you can demonstrate this, you're an agnostic. You believe in a god.
Then going by your definition, I suppose. Though I believe in my religion-specific God, and not just a higher being.
