Who cares? Many Americans are tired of getting black culture shoved down their throats by the entertainment industry and government. It’s all queers and blacks these days...
So you want the drugs, the LSD, the counterculture, the leftism, the degeneracy in music, but you don't want the traditional values?
Who was more conservative, the Beatles or Motown?
It wasn't back then. Motown dominated the music of the 60's,,,,,,like it or not.
Motown succeeded because its music was written and performed by talented blacks but was geared to Americans without regard to race and without drug influence and messaging.
