From Ms. Magazine:
What motivated Margaret Sanger and Estelle Griswold was more than a simple desire for freedom in this most private of matters — the decision of whether or not to bear a child. These pioneers of modern feminism also understood that the ability to plan and space one’s family is a necessary condition for women to achieve equality in all walks of life.
So much is at stake. Before birth control and abortion were legally and readily available, the average woman would become pregnant between 12 and 15 times in her lifetime. Even today in the United States, nearly half of all pregnancies remain unintended, and nearly half of those result in abortion. This is why polls show that the vast majority of Americans reject the extremism of a determined minority and do not want the Supreme Court decisions that protect their private decisions to be overturned. Doctrines of privacy and equality for women are simply not separable: Eroding one imperils the other.
And all this rests on the shoulders of just one new justice.
