I think with America it’s a different beast to most of the rest of the world. In that it presents as one country with several different states, but those different states can make their own laws and it seems a blanket law for the whole country can never be successfully applied. So whilst those in built up city areas can argue Guns should be banned outright due to the issues they so obviously cause, those further afield who may rely on their firearm for survival (hunting, farmers keeping away predators etc) will steadfastly disagree. Because there is such a huge disparity in the way of life between many states it’s difficult to get a clear consensus on the issue because, for example, somebody who lives in New York has a completely different way of life to somebody who lives in Back Swamp Louisiana.
Video games can I’m sure, cause a young impressionable mind to become desensitised and add to that online chat where children can be groomed to almost any cause it may lead a person to radicalisation (of varying forms) but that does not mean Video Games to Gun Violence is a certainty. Nor does the blanket excuse of MH do the issue any favours.
I’m sure most people would agree that an individual who is capable of gunning down innocent people is unhinged, but the MH isn’t the issue there, it’s the ease of access to deadly weaponry without stringent checks and controls in place.
