Yet you are talking about individuals, those founding fathers.I was not talking about individuals and Quakers. The founding fathers and the mainstream position in American society were for slavery. For example, Thomas Jefferson owned over 600 slaves and he was one of the authors of the Declaration of Independence in 1776 which states that all men are created equal. They meant all white men. American women didn't get the right to vote till just 100 years ago.
As of women's right to vote, this is a part of overall universal suffrage movement, which is the result of government progressive encroachment into everyone's life. If a government only concerns itself with protecting people's life, liberty and properties, we don't need so many to vote. A democracy that only allows 40+-year-old men to vote would have been more than sufficient. It is only when the government neglects the duty to protect women's life, liberty and properties, women need their voices to be heard.
