Obviously, not all people are the same. The whole point of a relationship is learning how to read your partner. Not everybody behaves the way that you want them to or approves of. It’s not about “scamming” somebody, it’s about genuinely figuring out what a person needs. That’s actually a good thing.
I don’t think it’s kind to make sweeping statements about who is “maladjusted.” People like different things. There’s nothing wrong with that. We shouldn’t judge them.
When a person is uncompromising, that’s considered attractive. My article doesn’t say to scam people, it says that part of cultivating strong romances is to put your own ego aside and learn what your partner wants.
