In the most basic terms it was about how when we experience art without critical awareness we consent to the ideas being promoted, either intentionally or unintentionally, by the filmmaker. For instance, if you watch a racist comedian and laugh at his jokes, you are consenting to the prejudices inherent within them. Similarly, if you watch a movie which perpetuates conventional ideas about race, gender, etc., you are consenting to them and not affecting change in any way.
