Answer 2

The sentence that shows that the speech is addressed to primarily female audience would be: We do not propose to petition the legislature to make our husbands just, generous, and courteous, to seat every man at the head of a cradle, and to clothe every woman in male attire. 
I put a highlight on the phrase our husbands. The sentence basically created in order to put a sense of shared experience that every female audience could relate. This type of technique commonly used in order to make the audience feel a sense of unity from the shared experience.
