I'm a relatively attractive guy and I've done this very thing before just to spite a girl I barely knew. In fact, when my girlfriend isn't around I like to do this thing where I'm really rude with polite language which makes them take a second before their silly little heads catch up to it. I'm casually misogynistic because of all the stupid "girls are better" bullshit they put us through in middle school. It made me really angry for a long time, but now it's actually very funny because there are subtle ways I can be abusive and shitty with no repercussions, and since I live in a city I get to do it all day long to these miserable cunts.
The "revenge fantasy" these robot types are on about isn't some far-off violence, either. It's literally birthrate collapse, which you see happening across the world, even in developing nations and places famous for fecundity like India.
