what does this quote mean?

Question

"When I look at human beings as moral beings, all distinction in sex sinks to insig- nificance and nothingness; for I believe it regulates rights and responsibilities no more than the color of the skin or the eyes. My doctrine, then is, that whatever it is morally right for man to do, it is morally right for woman to do. . . . This regulation of duty by the mere circumstance of sex . . . has led to all that [numerous] train of evils flowing out of the anti-christian doctrine of masculine and feminine virtues. "

From Angelina Grimké, Letter in The Liberator (August 2, 1837)

Answer 1

Here's the central idea for the whole paragraph:
My doctrine, then is, that whatever it is morally right for man to do, it is morally right for woman to do.

Laws, practices, duties -- all should be based on that idea, the equality of the sexes.
