That's another question.Yeah, it's hard to ascertain what is considered normal (or abnormal) nowadays...
If you've got a higher attachment to something, but it doesn't dominate, it's probably not abnormal is it? Just within a "normal" range.
But if you're on the receiving end, the amount of attention paid to that aspect would end up being abnormal. If you speak up, then every guy saying "but I only said I like Asian girls" gets defensive.
If the dating app technology is not allowing for that, it could become an app that many Asian girls don't want to use. That seems to be what they are saying. I could be wrong, I dunno. Maybe the app developers need to think about what they are trying to achieve or how they want it to be used.
