Total nonsense. 99.99% of people who play those games and watch those movies/shows don’t kill anyone. There have always been, and will always be crazy people. What video games were Hitler, Pol Pot, Mao, Stalin, etc playing? Are you sure it wasn’t heavy metal ...or maybe Elvis?
Oh, dont get me wrong, that’s my view as well. I just wanted to point out how the sacred cow of the left (the entertainment industry) could easily be pegged for incidents like this because people can just blame those mediums for making killing seem so easy, but you will never hear one Dem raise a finger at them.
