No, I amend that. Another example of this kind of society is the Soviet Union, in which authors could be censured and persecuted for writing something the authorities didn't approve of (Boris Pasternak, Aleksandr Solzhenitsyn) or composers could be reprimanded and denied performance for writing "the wrong kind of music" (the Zhdanov decree in 1948, condemning Shostakovich, Prokofiev, Khachaturian, and other Soviet composers as "formalist" and "antipopular.").

What you are advocating, WAV, gets pretty close to this: wanting to discourage or prevent people from singing "the wrong kind of songs."

If you want to go a little further into history for examples, there was a time when one could be burned at the stake, not for what one did outwardly, but for not having the "correct" beliefs.

No. That's not the way the world should go; not the way any country should go. That's a big step backwards on the road to civilization.
