My parents let me play Doom2 and Duke Nukem 3D when I was 10 or so. By early teens I was playing Soldier of Fortune.
Violent video games don’t create violent people. Only in the US judicial system would an assertion as stupid as that carry any weight. Using violence to solve problems IRL is a choice and if you aren’t prepared to suffer the consequences of making that decision maybe you should look for another way to solve your problems. This is called being accountable for your actions and American kids aren’t taught this in schools anymore, everything is someone else’s fault. You can pass the blame all day long but there’s only so many people you can throw under the bus before you end up under it yourself.
