Commenting upon IOZ's post linked above is Philboyd, who has a corollary formula which really resonates, and which I believe states with elegant brevity a position which is often difficult to understand, especially for those of us with the imperium and auctoritas of acculturated dudeliness:
Every piece of subtle macho posturing, every little joking intimidation would not work without the accepted social position of men as powerful studs who take what they want. Likewise, that accepted social position would not make sense without the awful prevalence of men raping women. Here, maybe, is a radfem twist: even if you don't posture, even if you try to repudiate the idea of a strong, rape-y man, your interactions with women still rest on a foundation of rape - just as a policeman who tries really hard not to use his nightstick still interacts with people on a foundation of violence. In our society, that's what a policeman is.
I don't believe this is easy for most of us men to understand. I certainly have had difficulty appreciating what it means to live as woman within the confines of a society which authorizes abuse of women as a norm, sexualizes it as entertainment, and politicizes it as a natural order of things.
