Along a different track of thinking, from where did rock music originate? Slaves. They created the guitar because slave-owners didn’t allow them to make music with drums.
What the flying fuck? The guitar is one of the oldest mediterranean instruments. Naturally it evolved from antiquity, but just how did you think that?
That attitude stems, naturally, from association with sex, drugs and pacifist rebellion with rock music. Organized religion often supports sexual morality, is suspicious of drugs (when it doesn’t incorporate their usage), and considers the social hierarchies to be of divine root, thus going to war would be the right thing to do and pacifism would be the opposite.
