Dude I'm sorry that you had such a scarring incident as a child. I plan on really encouraging my kids to play team sports from an early age, as I think they do encourage kids to think/act from a cooperative perspective and learn to handle both victory and defeat gracefully in life. But obviously I don't want to traumatize them into adulthood either. From my experience, that tends to happen when parents force a particular sport down their kids throat, or when they place too much emphasis on winning (i.e., living vicariously through their kids). So hopefully there's a positive balance to be obtained.
