Zero, you raise a lot of good points, as usual, but I still think the situations are different.
I've heard many people say, "I only watch NASCAR highlights for the crashes." I've never heard someone say, "I only watch NFL highlights for the hits." Yes, the NFL highlights often treat us to great hits, but they also provide a smorgasbord of other options: long downfield passes, spectacular touchdown catches, broken tackles, leaping endzone dives, etc. While we all take pleasure in the big hits, many of us cringe a bit too, hoping our favorite players haven't been put out of the game. By contrast, NASCAR highlights are composed primarily of crashes (with maybe a few cool passes sprinkled in), almost all of which put the contestants out of the race, yet I watch people taking outright glee in the crashes, whereas most people shudder when a big hit in football causes potential for injury.
By the same token, while I'm sure there can be a lot of excitement in a NASCAR race ("Turn left . . . turn left . . . turn left . . . turn left . . ."), I've heard many people say they don't consider NASCAR a true sport. I've never heard anyone but the most ostentatious of Eurosnobs deride football in such a way. ;)
As for my aunt being my uncle, I can't help it she's post-operative! :ahole:
