 As mentioned above, there are a variety of interpretations—feminist and otherwise—of what exactly oppression consists in, but the leading idea is that oppression consists in “an enclosing structure of forces and barriers which tends to the immobilization and reduction of a group or category of people” (Frye 1983: 10–11). Not just any “enclosing structure” is oppressive, however, for plausibly any process of socialization will create a structure that both limits and enables all individuals who live within it. In the case of oppression, however, the “enclosing structures” in question are part of a broader system that asymmetrically and unjustly disadvantages one group and benefits another. So, for example, although sexism restricts the opportunities available to—and so unquestionably harms—both men and women (and considering some pairwise comparisons may even have a greater negative impact on a man than a woman), overall, women as a group unjustly suffer the greater harm. It is a crucial feature of contemporary accounts, however, that one cannot assume that members of the privileged group have intentionally designed or maintained the system for their benefit. The oppressive structure may be the result of an historical process whose originators are long gone, or it may be the unintended result of complex cooperative strategies gone wrong.
