Elizabeth Cady Stanton, the feminist leader who spearheaded the first feminist and woman's liberation movement in the United States couldn't contain her firm belief that women were highly superior to men as beings. She boasted about it in her letters as you can see in the photo and which you can find taken from the full collection of her letters on page 270:
"We are, as a sex, infinitely superior to men"
Here is her bio:
"Elizabeth Cady Stanton (November 12, 1815 – October 26, 1902) was an American social activist, abolitionist, and leading figure of the early women's rights movement. Her Declaration of Sentiments, presented at the first women's rights convention held in 1848 in Seneca Falls, New York, is often credited with initiating the first organized women's rights and women's suffrage movements in the United States."
