Have you ever read Catcher and the Rye? Society's morals were already corrupt in the 1940s-1950s. It's just that they censored TV so that TV life was not degenerate.
The leader of my religion wrote this 1947, regarding the "rotten morals of the present world":
"What Baha'u'llah means by chastity certainly does not include the kissing that goes on in modern society. It is detrimental to the morals of young people, and often leads them to go too far, or arouses appetites which they cannot perhaps at the time satisfy legitimately through marriage, and the suppression of which is a strain on them. The Baha'i standard is very high, more particularly when compared with the thoroughly rotten morals of the present world. But this standard of ours will produce healthier, happier, nobler people, and induce stabler marriages. The Master's words to Ann Boylan, which you quoted, can certainly be taken as the true spirit of the teachings on the subject of sex. We must strive to achieve this exalted standard." -Shoghi Effendi
