Video games don't drive anything but laziness. What drives mass shootings is political exclusion. More and more, people are victimized by Orwellian and oppressive government, and no longer feel able to do anything about it. Most Americans, when it comes to interacting with their government, have learned to keep their head down and take it, and walk away. When your people are blamed for things, their contributions derided, and you are personally subjected to social stigma and organized abuse, and you cannot get help and support through political avenues, that is what drives despair.
Anger is the child of fear, and suicide is the child of despair. Additionally, most mass shooters have been diagnosed with emotional disorders, and have close associations with people in government service, particularly FBI or CIA. Given Epstein's revelations, and apparent 'intelligence' involvement in his sideline, it is not especially outrageous to suspect such vermin to push their own kids to commit outrageous crimes, or involve them in outrageous plots.
It is a truism that some people consider most or all of them to be political acts, and false flags used to tar the race, gender, or political affiliations of the shooter(s). There certainly are people that will sacrifice their children to their own goals, and finding some of them involved in agencies that are kidnapping, raping, and torturing children professionally shouldn't be surprising. What do you think MK Ultra was about anyway?
Few video games involve shooting ordinary people, or children, in gun free zones. None I can think of, or have even heard of. Most of them involve some kind of monsters, or armed opposition, that is challenging - fun - to defeat. Mass shootings do not resemble video games at all. Play one and see.
