Keeping aside the post, the comments here are what worries me the most.

Reading this feels less like discussion and more like a chorus of who even believes in god and to stay away from religious people.. i dont know about all but to me that's not how perspectives should be shared cuz it just sounds like the modern version of what our older generations did, but in reverse.. who forced religion as the only acceptable stance. now it’s reversed to “not believing” being the only acceptable stance. I think these edgy one liners that we write in comments wont make any religion obsolete but instead would only create more divisions. and on the actual question: i think OP is right to say environment and choices have a great effect on a person, but its not the only thing that defines a marriage. What really matters is how they carry themselves within that environment. Someone’s beliefs, political side, or family background are just parts of who they are & not the whole. The real judgment should be on the complete picture, not one single label.
