Social critic: The whole debate over the legal right of rock singers to utter violent lyrics misses the point.
Premises
(1) The legal-rights debate misses the point. (2) Legally, very little can't be said. (3) But not everything that may legally be said ought to be said. (4) Violence predates this music, but words have the power to change how we see and act.
Evaluate
Notice the critic's structure: legal rights are not the question; what we ought to do is. And words can change behavior. Putting those together: even if violent lyrics are legal, voluntarily not producing them — i.e., self-censorship — could change the way people see and act, which could in turn reduce violence.
Goal
Find an answer that says: voluntary restraint by rock musicians could help reduce violence in society.
