After seeing topless protesters hijack Bernie's rally in Nevada, I can't help but fit that into the broader pattern detailed in an earlier post about how political junkies are boob men and women. The men fixate more on T than A, and the women are either busty or at least favor displaying their boobs rather than ass to an audience. The explanation is that political junkies are cerebral, which is correlated with being a boob man / woman, while corporeal people tend to be ass men / women.
That post drew on evidence from social media personas, but here we see the same pattern emerge in a different context (IRL protests).
In fact, these women protesting dairy farming are only one example of a larger tendency toward topless protesting, most notably the FEMEN group (they're Slavs, so they don't have either T or A, but always chose to display the top rather than bottom). Then there was the #FreeTheNipple thing. Both of those were part of the Slutwalk era during the last manic phase of the excitement cycle in the early 2010s, before the Me Too phase of the late 2010s.
Incidentally, the re-emergence of topless protests is another sign that the vulnerable phase of the cycle is over, and we're now in the restless warm-up phase. No way this could have happened during the height of Me Too, when women in a refractory phase felt hysterically vulnerable to unwanted sexual attention. Nor is anyone in 2020 going to call Bernie rape-y or molest-y for staying on stage with topless young women, rather than averting his eyes and making a bee-line for the exit like a good male feminist.
Earlier there was bra burning during second wave feminism. Streaking during the '70s was not political, and in any case cannot resolve the matter because the entire body was shown, not only one area or the other.
When only one region is shown, it's always about taking off their tops, not baring their buns. Nothing prevents them from taking off their underwear, or wearing a g-string or something, and twerking around on stage. Or only pulling down their pants enough to moon someone. The fact that mooning is already a widely established form of revealing private parts to diss someone, and yet is never done during these racy protests, shows just how inclined they are away from the back and toward the front.
