I went to college too, and guess what? I don't agree with you XDDon't know why I'm getting involved.
No, actually you didn't. Murder culture is a thing. Many shows do promote it, though it's often more generally included with "culture of violence" which yes, we do have, yay wild west/civil war/revolutionary war roots.

Rape being illegal doesn't mean a country doesn't have a rape culture. Rape culture is about how sexual violence against women is tolerated, denied, or promoted through language, actions, government and social interaction.
But most of the dips in this thread are just keyboard warriors and have no idea what they're talking about. There's a reason I'm 30k in debt for college and I don't have time to explain it in detail.
