There is a strange religiosity applied to the concept of family in US culture. I originally started writing “Midwestern US culture,” but most of the examples that come to mind aren’t confined to the Midwest. There’s an entire line of movies (The Fast and The Furious) that is all about the primacy of the family unit, though they tend to define family a bit more broadly than most. There’s entire cultural background covering the importance of The Family as it relates to organized crime. One of the most popular types of stories these days is about found family or the lengths to which one might go to return to family. Family, regardless of how it is defined, is seen as something worth everything and valuable beyond measure. What makes this somewhat more sinister and unpleasant, though, is the suggestion that anyone lacking family is a bad person. Villains are frequently loners. The philosophy of those we’re supposed to dislike is often depicted as favoring isolation and a lack of attachments. Hell, all you have to do is look at advertising and media around the parent-oriented holidays (Mother’s Day and Father’s Day) to see the subtle suggestion that choosing to ignore your biological parents, or otherwise hold the way they treated you against them, is a moral failing. It’s pervasive.
