Why Is White Establishment So Afraid Of Rock, Soul And Blues?

I was mulling over possible reasons why is that such different political ideologies as American oligocratic capitalism and Soviet gerontocratic communism were so averse to rock, soul, reggae and blues music? The hate affair in America ended as soon as Black music started making money but in the USSR it held out until the country's collapse. That said, on the Stateside, even when after a long struggle Afro-American music became mainstream, the still-very-much-alive all-White Disco Sucks movement would sometimes erupt in outbursts like the infamous Disco Demolition Night.

I think it is the overblown perception of African sexuality as the sexuality of the Other that created the notion of actually any darker-skinned people as being early sexually mature, promiscuous and more potent. This idea has pervaded Western world since the time records started, i.e., Ancient Greece and Rome. African beat based music have thus bothered White hetero male establishment on both sides of the Iron Curtain as subconsciously associating with sexual licence, which powers that be naturally resent - ideological control of sexual activities is one of the powerful tool of mass manipulation.

Ironically, those who share this sentiment with the White establishment are those who are most abused by them : White undereducated blue-collar workers.
