Friends of the pod, could you help me with examples, contexts and ideas for the "aggression in media" uni course?

Long term BtB listener here, I was assigned this year to teach a course about aggression/violence in media for media communication students. I still have some time to prepare and I have a general outline for the semester - but as always, I could do better with more examples and more context. Therefore I'm asking probably the best equipped hive-mind, could you throw some examples at me?
Note: please do not share anything that could ban me or you ;)

I'm interested mostly in images (significant symbols, memes, visual rhetorics), web articles, any interesting trivia (modern or historical). To lesser extend academic articles and academic theories - but those are welcomed too.

I intend to cover following topics:
- general mechanisms of violence and aggression in media (sociological take)
- hate speech (definitions, limits of free speech)
- metaphors of violent and coercive language
- moral panics
- tribalism
- internet aggression, unique characteristics of that medium(s)
- visual rhetorics
- censorship, omission, what is not said and invisible
- genocides :)
- agonism versus antagonism, is there any way out

First and foremost, I need to design an interesting course for my students, which can be a challenge with heavy sociological theories - so I think I need to rely on good and relevant examples

I will appreciate any help, even the smallest recommendation, like a meme or a link.
