I dated someone, he mentioned it on the 4th date (after 1.5 months of seeing each other). We were cuddling in bed, we were talking about honesty and communication, he told me "Speaking of which, I want to tell you something", I told him "What? you have a wife and a kid?", He said, "a wife no, but a kid, yes, he's 10 years old, and I've been separated from his mom for 8 years". I told him, "why didn't you include it in your bio?", He said, "would you have swiped right on me?".

I got his point, and I understood it. Before meeting him, I would swipe left on all those who had children, but after I met him, I got to experience what it's like, and I am now different. We all are on some level judgemental over things we are not familiar with, specially on OLD where one is basing their decision of a select number of things without context.

I also understood him on a deeper level, maybe it's an insecurity of his, I have one too. I come from a muslim background, and dating in the western world, even though I am agnostic and well integrated in my society. I know a lot of people that wouldn't choose to go out with me based on this sole fact, out of preconceived ideas and bias. Would I put that information straight up on my bio? No. I'd like people to get to know me for who I am, and then make a decision. This information usually comes up usually during the first few dates.

It's not black and white. Yes, facts should be revealed in the very early stages of dating, but to mention things in bio or during chatting before meeting? I wouldn't. And I understand people who don't.
