That is NOT my position.
My position is that sport is wonderful (I've said so) that sport is a good way to deflect aggression into harmless competition (I said so in my first response) that sport is a healthy outlet for frustration, a great way to build strength, stamina and co-ordination. Sport, particularly team sport, is good training for children to learn rules, co-operation, self-control and how to cope with disappointment. It's a primitive but reliable assessment of adolescent males for their status in a masculine hierarchy (if you must have those) and an even better means of bolstering the confidence of adolescent females. It's also fun, both to participate in and to watch. A home team inspires loyalty and pride of community. I may have left some stuff out, but the main theme here is that sport is wonderful (I've said that already).
What's bad is commercializing it, turning it into a spectacle, exploiting athletes and driving them to self-destructive behaviours in pursuit of winning, isolating them, wrecking their childhood and social life, idolizing them and commodifying them at the same time. What's wrong is turning a joyful leisure activity that everyone should enjoy into a profession and a business. That's wrong.
