> Institutions do not form spontaneously, and the "systems" you refer to were also created by humans. The notion that men created systems and institutions which oppress women, but it is totally not a conspiracy because they did it by accident is not well represented in feminist academia.

It seems like you are saying that is there is indeed a real conspiracy of institutions created and/or controlled by men, in which case I totally agree. We have well documented cases, historically and in the present, of institutions and systems that are dominated by men.

> Except that alternative explanations are dismissed. If the "evidence" supports many possible conclusions, then it is not proof of a single specific conclusion like "patriarchy".

I've yet to see convincing alternative explanations. All of the evidence points to existence of patriarchy as a social institution.
