Boycott rock fundraisers
(Live Aid; Live 8; etc).
Explain that rock stars have an unerring ability to choose the wrong causes. The original Live Aid event, for example, might have killed at least as many Africans as it saved by encouraging Ethiopia's Marxist dictator Mengistu Haile Mariamin the Stalinist "land reform" program that had caused the famine in the first place.

Psalms 118:8 It is better to trust in the LORD than to put confidence in man.
