Fareed speaks with Malcolm Gladwell, longtime ‘New Yorker’ staff writer and best-selling author of ‘The Tipping Point’ and ‘Outliers’ about American college football – and whether it’s time to stop it altogether. Watch the full interview this Sunday at 10 a.m. and 1 p.m. ET on CNN.

You compare football to dog fighting. Why?

Yes, I did a piece for The New Yorker a couple of years ago where I said it. This was at the time when, remember, Michael Vick, was convicted of dog fighting. And to me, that was such a kind of, and the whole world got up in arms about this. How could he use dogs in a violent manner, in a way that compromised their health and integrity?

And I was just struck at the time by the unbelievable hypocrisy of people in football, for goodness sake, getting up in arms about someone who chose to fight dogs, to pit one dog against each other.

In what way is dog fighting any different from football on a certain level, right? I mean you take a young, vulnerable dog who was made vulnerable because of his allegiance to the owner and you ask him to engage in serious sustained physical combat with another dog under the control of another owner, right?

Well, what's football? We take young boys, essentially, and we have them repeatedly, over the course of the season, smash each other in the head, with known neurological consequences.

And why do they do that? Out of an allegiance to their owners and their coaches and a feeling they're participating in some grand American spectacle.

They're the same thing. And the idea that as a culture we would be absolutely quick and sure about coming to the moral boiling point over the notion that you would do this to dogs and yet completely blind to the notion you would do this to young men is, to my mind, astonishing.

I mean there's a certain point where I just said, you know, we have to say enough is enough.
