The sad fact is that whether we're talking about dating apps or just meeting in real life by random chance, many people are somewhat damaged. If it were possible to create an app that helped people be more empathetic, get past old hurts, and have a more realistic view of themselves, that would be great - but probably no one would use it. Meanwhile, as individuals, we just have to be as kind as possible, recognizing that even the most annoying people are generally operating out of a place of suffering.
