I have to say something about this video, taken at the Dallas Zoo:

It’s sweeping the internet. Most people think it’s great. It may be great, but its “greatness” comes from the power we see exhibited by an enslaved animal. Maybe he’s dancing. Maybe he’s exhibiting deep frustration at being caged. Maybe it’s depression, stress, or some other pathologic behavior shown by caged animals, something which I’ve learned actually has a name: zoochosis.

It reminds me of how Romans were entertained by gladiators. Most gladiators were slaves, placed in arenas to fight for the delight and distraction it gave their enslavors.
