A metaphor would be "the boy was a cat as he tip toed quietly through the house".
You're thinking about what reasonable people would say and mean, but these people actually want to say that seeing a trumpet getting flattened in a commercial is the same as watching your own pet be tortured. Why that is, is anyone's guess. Maybe to seem sensitive and deep.
Remember when I predicted that you would attack me and attack 'how I asked' for evidence instead of actually explaining how watching a commercial of a trumpet being mushed is the same as watching your own pet being tortured?
