Yeah, and I’m good with that definition. But the problem is that most people are just interpretating it as if it were “I hatr parties and she loves parties, so we’ll be the perfect marriage with no doubt”, while that will cause so many problems because of these are two ways of socialization that are in the antipodes of each other. I myself hate parties as I’m heavily introverted and, also, I’m autistic, so I don’t really get well in large groups or people (or even in small groups of people if I don’t know them), and I also just hate the ambience of a party.

Even with more small things it does apply. Like, I love anime, so I’d never date with someone who hates it.

And it obviously will be more important when it’s about trascendental things such as religion, political views or philosophical stances.

But most people just take it as “if you hate X, you have to date with someone that loves X” or “if you love Y, you have to date with someone who hates Y”; that’s not how it works.

True complementarity needs to be built upon a strongly shared core of expectations, values, thoughts, ideas, visions of the world and ways of living life, because otherwise there will be little or not intelligibility.
