War documentaries that glorify violence are propaganda.
We shouldn't ban them, but we should contain them the way we contain all propaganda - study it's means to an end, and contain it.
I'm pro rioting. I don't know why you think I'm triggered. Rioting isn't promoting violence. There is also a question of instigation.
Person A: Punches person B in the face
Person B: Punches person A back in return.
These actions are not equivalent. A instigated. B defended. A is being violent. B is not.
Person B: Destroys person A's property
Person A: Punches person B in the face
These actions are not equivalent. Person B did not perpetuate violence. They instigated, but A did not defend - they escalated from property damage to personal damage. B is not being violent. A is.
This ain't rocket science.
