> They could sometimes admit that women were oppressed (but only by “the system”)

As the saying goes, when you're privileged equality feels like oppression.

Yup.

Somewhat amazingly, John Stuart Mill addressed this as long ago as 1869 - a full hundred years before The Personal Is Political, in his essay The Subjection of Women:

> “But was there ever any domination which did not appear natural to those who possessed it? ... Those who enjoy the benefit of an institution or a social arrangement, have a strong interest in believing that it is just; and they are rarely slow in finding arguments to convince themselves of what they wish to believe."
