Your damning indictment of Hefner, and his crasser imitators, and their customers, supports my point. Hefner et al. found a way to corrupt the culture without depending on the force of laws, and guns, and polizei. Far more destructive.
IMO.
Hefner did not force his ways on people, they gladly accepted them. He wasn’t devious or indirect, he was very direct. Which says Hefner didn’t corrupt anybody, they corrupted themselves.
Put it another way, if a mere magazine with images of nude women could corrupt an entire population of people then just how moral was that population in the first place?
