Yup, that’s one flavour of propaganda. Others include racism and xenophobia, all different kinds of fear mongering from stealing jobs to raping “your” women, flat out lies like people eating pets, nationalism, exceptionalism (sadly not only an American problem), and so on. It is everywhere in pretty much all the media we consume consciously and un/subconsciously, even the most left leaning people can’t completely avoid it, we just work harder at being aware of it and (in general, should) do our best to combat it in our own minds and the minds of others.
