And how exactly is that supposed to be actually done in practice, nevermind to the degree that would even begin to match the spread of rank tendentious garbage achieved by this blockbuster movie that so succesfully appeals to the primal urges and encourages the audience to switch off their higher faculties ?

That is specifically why I so loathe this kind of macho populism in entertainment. It's like a weed - spreads fast and wide, and is an imperial pain to get rid of should that even be possible.
