I've been playing FPS games like Battlefield, other "violent" video games like GTA series and lately Assassin's Creed and Ghost Recon. I don't have any compulsion to go and mow down hookers after playing GTA. Anyone who can't differentiate a game from reality is nuts. I should note that I hunt and taking any life is a very serious thing. I don't take it lightly.
I don't doubt that some (many) are so disconnected from reality due to the fact that they do not live in the real world, social media obsessed idiots. Those people would be easily desensitized to violence because they're already living in la la land. Killing any living thing, be it a human, domesticated pet, or wild animals, is infinitely easier if you don't respect life in the first place. MK Ultra tools.
