Betty goes at it full-throttle in this scorcher. She leaves it to interpretation but here's a few sketches of possibilities.
If the 60's was the Empowerment decade -from King to X to Che to Chavez to the Counterculture- then the 70's was the Liberation decade. There were so many issues to address that what we know of as the 60's really stretches roughly from 1964 to 1975. The rise of Feminism and the lateral expression of sensuality were later, crucial extensions in that period.
Sexism is evil; but Sensuality is essential. The word "sex" can mean either gender or the sensual act. Folks who blur the two without distinction speak to neither well. Gender inequities are wrongs that should be righted. Sexuality is a spiritual and physical pleasure everyone has a right to. The best lights of Feminism understood this from the beginning, and do now with examples like Riot Grrl and Bust and Bitch magazines. Betty Davis was a progessive sensualist who was misunderstood and suppressed in her time by repressives and some confused progressives. Time has borne out the quality of her work and the merit of her stance.
