I don't think what you wrote was pointless or meaningless
And hey, at least this one won't be derailed by gun debate.
I suppose you have a point. In 1929, right before the St. Valentines Day Massacre I read that January only had 26 murders on record. Those numbers are almost doubled in recent years on a per month basis. 1929 didn't have the gun control we have today. Of course in 1929 you didn't turn on the T.V. or watch a Movie 24/7 with nothing but killing on it or stories about killing.
If movies, TV shows, or songs had a powerful or meaningful-enough impact on people to kill each other (and all the other bad stuff), then these things would be more wide-spread. Instead, it's mostly in the gang-infested areas where people are shooting at each other. I'm not saying it doesn't happen in other areas....I just don't think you can blame the murders in Detroit or wherever else on music and TV....since it's pretty much only happening in those specific areas.
It's not so much the impact or motivation, the impetus, as it is the normalization of violence, the numbing of empathy, and the remoteness of the individual from their expected interaction with others. IMO, anyway.
Tv, movies, and video games are teachers. You don't have to imagine what it is to kill others. You can experience it a hundred times an hour in rpg's. See it depicted dozens of times per movie. The culture, not just the gang culture, which is a dog whistle, of our America has made a world of You and all the annoyance of putting up with others (in Star Trek they were Red Shirt crewmen) unless there's something you want from them. It's well down the road to being a psychopath. And most of us are standing on that road, desensitized, self-centered, alone...
Well. I'm depressing the hell out of myself even trying this conversation. Move over, monet. I'm going to sideline myself and enjoy the new neighbors screaming at each other in the middle of the night yet again.
