The Family/Gender/Sexual Revolution is a complex phenomenon, but there are signs that the rejection of traditional values continues to spread--50 years after it began.
Here are the percentage of Americans who think that various actions are morally acceptable, measured at the beginning and the end of the last decade (from Gallup):
Percent thinking the behavior is morally acceptable
Sex between unmarried man and woman
Having a baby outside of marriage
Gay marriage should be valid
Attitudes toward gay marriage have changed most dramatically, but this issue is just the most recently-grown leg of a monster that was born in the Sixties. The new ethic replacing the traditional one claims that any kind of relationship is good as long as it is honest, voluntary, and egalitarian (infidelity and polygamy are as condemned now as 10 years ago). Any limitations beyond that are considered judgmental. Questions of what is good for children or what is good for the country are irrelevant. Freedom from sexual rules, self-fulfillment, accommodativeness, egalitarianism, and androgyny are the new idols. The new Prophet is half Beatnik, half Woman.
