square, do you think men and women congregating is always leshem shomayim? isnt it usually – actually, almost always – just to hang out and be untznius? thats why pizza stores and other hangouts are bad. they facilitate inappropriate relationships. the pizza stores arent holding singles events. if they did, it would be like the women on YK and tu baav; rare accomodations for rare circumstances.
“organically” – you mean they met based solely on their initial chemical reactions to one another and built a relationship around each others physical appearance, only for it to deteriorate once that appearance fades and/or the middos and hashkofda issues come out, leaving two people heartbroken and having wasted their time on a shidduch that never had potential – which could have been prevented had they used a shadchon/intermediary.
