Good point and yes I do see this being perpetuated predominantly by mass media but also the entertainment industry. Hollywoodism in particular is ruthless in maintaining not only human stereotypes and archetypes but also myths and falsehoods in efforts to normalize conformity and complicity. Much of it reinforces collectivized thought both subconsciously and on a surface level. All our ideologies and "isms" are based on this continuity and historically our progress is in fact eerily reliant on maintaining this method of existence.
Ironically this platform, Steemit is equally at fault. It prime existence is based not on knowledge or a medium of human virtual exchange but strictly on monetary factors and thus factors are dependent on the idiocy of the masses and their collective "popular" interests.
