The many, many people who claimed to have lost parents and/or grandparents to Fox would like to have a word with you. Their stories frequently tell of loved ones who used to be more conservative or old-fashioned than they were, but with whom discussion was possible even if they didn't always agree. Said stories invariably ended with mourning the process of those same loved ones turning into mouth-pieces for whatever stuff Trump or Hannity spouted the night before, often practically paraphrased, who were just angry all the time and who'd bring up the latest conspiracy out of the blue even if the dinner conversation was about something completely different before.
It's a little short-sighted to purely see Fox and its right-wing cousins as "unmasking mechanisms" for people who were crazy and evil all along, rather than as channels that take people's grievances and nurture them, validate, amplify and then weaponize them, all the while telling those viewers that trains of thought that used to be socially unacceptable are, in fact, perfectly acceptable because look, all these high-profile people in your media bubble are saying and thinking the same.
