According to what I understand the essence of women and men cannot be equalized, it corresponds to the different natures between men and women. But if viewed from the equality of obligations in a broader scope, then men and women have equal rights and opportunities.

This point you made here is absolutely true. But some people tend to misinterpret the point. Men and women can’t be equalized due to the difference in their nature. But that doesn’t mean that the difference in nature or other key factors makes men superior to women. When we try to look at things this way, then we are looking at it at the wrong direction.
