edward bernays intentionally used propaganda.

i have taken plenty of media literacy classes.

go study fatimah tobing rony. "race, cinema, and the ethnographic spectactle." this film had no ethnographic spectactles (xerxes might count) but it is a big stretch.

in her book you will find concrete examples with solid arguments about what you are talking about with "master narrative" and depiction of others.

300 isn't an example. you haven't provided an ARGUMENT you just keep throwing out red herrings and bringing up bernays and other bullshit. i feel sorry for your students because it is my guess that you subject them to this kind of one sided non critical thinking and force them to either adopt your beliefs or get an F.
