The argument over hierarchy is one of the most contentious ones in the polyamorous community. Many people find it important to label their relationships Primary, Secondary, and sometimes even Tertiary. Others are militant in stating that terms like that are unfair to those labeled Secondary or Tertiary. Some have used terms that attempt to remove the hierarchy, such as nesting partner or anchor partner, sometimes in place of the term Primary. The argument has been made that a nesting (cohabiting) relationship or a marriage automatically enforces a hierarchy, and those in nesting relationships are unable to be non-hierarchical.
This argument is rehashed constantly, probably second only to the argument over unicorn hunters. Something I’ve realized, however, is that often those that argue will end up agreeing on everything except what the term “hierarchy” even means.
There is a solution to this argument, and it lies in the concept of prescriptive hierarchies versus descriptive hierarchies.
