Also your post ignores the fact that torture can depend on the individual. Serving a prisoner bacon would usually be a treat, but what about a devout Jew? Would that not be torture to force someone to eat something that they believed to be a sin against their god? Devout Muslims (and many others) view watching pornography as evil. And again, we're not even talking about normal stuff. I doubt many people could be forced to watch something like 2 girls 1 cup and not consider it to be torture.
As for it's brevity, that's not a valid defense. It would be like reading the Diary of Anne Frank and saying only, "Being locked in a room isn't that bad". Claiming that this statement was brief would not excuse the entire lack of human empathy it took to say it. It's not just brief, it's intentionally ignoring tremendous human suffering.
Finally, something can be torture and not be the worst possible thing ever. Otherwise it would be clear that your definition of torture pales in comparison to the real thing. Burning? Cutting off someone’s ears? Decapitation? Those are positively luxurious compared to some thinks we've thought up over the years. Judas' cradle, flaying, the breaking wheel, the pear of anguish, the head crusher, the iron maiden, the Spanish tickler, and many many other torture devices are on an entirely different level of cruelty.
