I actually somehow got into a fight on a website with someone who believed Immortan Joe was the hero of the movie... even though I've never SEEN the damn thing.

Yeah, I think in a lesser movie he would definitely have been portrayed as the hero. Pop culture certainly looooves to portray violent, abusive asses as hard men driven by grim necessity. Even when he's all-too-clearly the villain there are people who insist he isn't, ugh.

Also, the whole "women are higher than men, because men want to bone them so badly" is a really common MRA trope

You also know about MRA grandaddy Will Farrell and his book The Myth of Male Power, right? Extra hate points for his incest apologia. Between you and me, though, I find "whoriarchy" strangely awesome.
