Just because patriarchy primarily benefits men, it doesn’t mean it’s all their fault. That said, it’s important to note that they stand to gain the most, meaning to get to the source you must identify and address those men than support it directly and out in the open.

You could say the same for capitalism. It mostly benefits those with capital, but literally everyone still struggles under such an economic system due to it’s core tenets of sacrificing personal well being and exploiting labor for maximizing profits.

Same goes for white supremacy. It mostly benefits white people, but it absolutely impacts them negatively, as well. Scholars will still tell you that white supremacy is defended and perpetuated by nonwhite people but the ones with the most power to defend and maintain systemic policies are typically going to be white (or funded by white people).

I don’t know how you dismantle a system without addressing it directly and understanding who it’s supporters are.
