It seems strange to say that confidently if you don’t even know what it means.

Equality is a nebulous concept. Equality of what? Because in a sexually dimorphic species there's one thing you can say more certainly than anything else: men and women are not equal.

In this instance it means that neither party is subordinate to the other. It does not mean "equal" in the mathematical sense that two things are identical. With this knowledge perhaps you can go back and make sense of the discussion.
