I was simply using slavery as an example, I know that's not what we're talking about: we're talking about equality. However, I'm not talking about things as they currently stand, I'm talking about how things ought to be:
You say man and women are not equal and in our current society they aren't, like you said we have unequal obligations but that doesn't mean that we aren't fundamentally equal. (which isn't a communist ideal, its a democratic one) I'm in no way saying that men or women are better than the other to quote the Declaration of Independence:
“We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.”
And remember, Thomas Jefferson is talking about Humanity, not just its males. This is what I believe, we are all equal. We may no be treated that way yet but at that time almost nobody was equal under the law yet either, I have hope for the future that we can figure out a way to live in true equality.
