 The anarcha-feminists argued that overthrow of patriarchal society was just as necessary for personal freedom, as the creation of a classless society.To demonstrate this new sexual equality, some women even fought at the front (no more than one thousand) and several more joined women's battalions in the rear.However, Michael Seidman argues that sexism was still present - in some collectives women were still paid less than men and could be denied voting rights, while single women could be expelled from a collective (as they lacked a more productive husband for farm labour).
