Actualized Defamation is the result akin to "call a person a monster for long enough, they will become a monster" but on a larger scale. When society or a powerful feed source within it presents manufactured or stereotyped information about one group of people, those people over time will become what they are told they are, even if the target group fights against or protests the propaganda/prejudice. Indeed the fight against the words cast about them can aid in speeding and further ingraining it as truth.
"Gay males are overly focused on sex and generally rebellious against safe practices, in my opinion, is the perfect example of actualized defamation. If they lived through the 80s and 90s, they had the media's AIDS obsession, the Christian Church's bible and evangelicals, and the general public's ignorance telling them from every direction they were 'plague spreading sexual monsters'."
