Defining gender was the original division of labor, the idea that women should rear children and thus reproduce the social relations in a primitive society is the original class divide. Engels describes this well in the Origin of the Family, Private Property, and the State.
These concepts aren’t distinct struggles. Class is the base and gender is a superstructure of that base. Struggling against gender based oppression is also struggling against the way capitalism exploits gender to reproduce class relations.
