Extraordinary claims...
But seriously, back this up with some evidence.
Compare the amount of violence today with the amount of violence a century ago. Oh yeah, that's also not citing any evidence.
Of course, this greatly depends on where you are. Arizona was still wild west, gold mines still hung folks they accused of stealing ore (Vulture Mine) Wars were still being waged between native peoples as well as banditos and cowboys holding up banks, transports, and the likes. Tombstone and the O.K. Corral was just over 100 years ago. And back then, media really wasn't an issue since the average person in these parts was 100% illiterate.
Not to mention in the past 50 years, violence and violent crime in the US is at a near all-time low compared to the 1970's or 1990's.
Also explain how more peaceful societies, such as the Dutch, or the Norwegians, consume more of our violent video games than we do?
And yes the amount of violent activity in games far outweigh that in real life but there is another huge difference. Games are not real and even the most naive of us have a very clear differentiation: there is no respawn in real life.
