What Is a Mato Normativity?

A mato normativity was coined by writer Elizabeth Brink and it's basically the idea that romantic and sexual relationships are the absolute pinnacle of all relationships. For me I found that a matonormativity leads people to devalue other important relationships. Not just romantic ones that aren't sexual but also friendships and family relationships. That may keep us from forming strong communal and family bonds, friend bonds and queer platonic bonds etc.
