The context is this rather disturbing photo where a man has loaded a photo of a woman onto his phone and ejaculated onto said phone with the caption "This is your true purpose." The "crime" of the woman in question appears to be supporting the campaign to repeal the eighth amendment.
At first, I thought "ew, I wouldn't want to work at the phone shop when he takes that in for repair". Then I felt really quite disturbed, so I had a think about why.
I'm reading his defacement of her image with his semen as an attempt to degrade her. He can't degrade her in person through rape, so he defaces her photo with his semen and shows her (by publishing the photos) that he has done it. I think this could be called "rage wanking", because he didn't do it for sexual pleasure, he did it to degrade her, and it's on a continuum of "penis as weapon" male violence against women with rape at the severest end and "choke on my dick" at the least-severe end.
AIBU with my analysis? And AIBU in thinking this man would try to rape the woman if he had access to her? My gut feeling is that he would try it.
