There is more to "sports" than watching them on TV. How about participating in them? It's good for your health, sort of like not eating McDonald's.
>If I don't eat at McDonalds because I care about my health, am I unfit for socialization?
There's a difference between "not eating" (or "not liking"), and "showing overt contempt" towards.
So, yes. If you don't understand that, your social skills are probably lacking.
The context here -- starting with the article, and followed in the thread prior to your response -- was participation in the culture of fandom of popular professional sports.
Obvious, individual direct participation in sports is a completely different thing (and often a thing that competes with participation in fandom culture.)
I haven't seen a single case where being a fan has precluded children from going out and playing.
Perhaps as adults the situation might be different, but their are a whole host of other factors at play there, including health and time issues.
