Not dating, but socialization. We are so lonely and isolated, and economically stunted, that we have issue interacting and building any type of bond. And then add a pandemic where the only interaction was your family.
To be clear, what i am trying to say it goes beyond dating and there is a systemic issue.
OG Nazis experienced the same thing. Killing people on en masse mentally fucks with your head, even if the individuals you kill are perceived as vermin/degenerates. This is why they moved on to using other means that is more dehumanizing i.e. pressing a button for the gas chamber
