CTE has been found in high school players.

As for violence in society, that is mostly an artifact of our culture. We are a warlike nation. Football is popular because Americans are morbidly fascinated with violence, and the game has many of the characteristics of war.

@Flyingsaucesir is right about that for football. Soccer is not quite as violent but certainly as competitive and physically harmful. Steady diets of war, horror, gore, guns, and savior heroes (from whatever medium) have created this culture. It will take decades to lose it and mass shootings will happen until we do, I'm afraid, but it won't happen at all if we don't put forth the corrective efforts. At this stage of stalemate the efforts will need to be radical. Dems are far too sensitive and obedient for the likelihood of such efforts to spark.

I think it will fade because of not being so brutal. That's the attraction and it's a strong one. I lost a good friend because I called him out on his refusal to stop with NFL while proclaiming how whites are automatically racist. He's on two marriages with Latin international women so believes romantic interests indicate he's transcended the issue. I think he merely enjoys being subordinated and uses race as cover but I'm cynical. Anyway, the game might become the domain of VR.
