The definition centers around the term «equality» of the sexes. I am unsure what this means. Obviously there are great differences between the sexes that deserve respect. These differences will also manifest themselves also socially , economically and politically. And there are similarities. But is this the point?

«Equal worth» seems much more accurate than just «equality». The feminine and masculine qualities are obviously wonderfully different in manifestation , socially and politically and economically , while it would be insane to claim one to be more worth than the other. They are the basic elements of all life as we know it.

Different in form.

Of equal value.

And they are vastly more valuable when working together in harmony.
