I played football and yet never drink, have never done drugs, am not and was never homophobic, never got into trouble etc.
Would I let a kid play football now, with all the knowledge of CTE? No. I absolutely even worry about it for myself. But it's a bit odd, to me, to say "football made me a bad person".
I think basically all people who were socialized male have had these experiences at one point or another, whether it be in football, in class, in the military, at sleepovers, in the locker room.
My point is more so that football has a particular “culture”, or it did when I was a kid. And that culture was not necessarily socially productive at a young and impressionable age. When we see certain behaviors in particularly young men, we have to wonder where they come from, and what we are doing to cultivate that.
