First two may not specifically be protest songs:
Goodbye Daughters of the Revolution - The Black Crowes (you could shorten it up to be "Daughters of the Revolution")
American Girl - Tom Petty and The Heartbreakers
Daughters of Freedom (protest song from the 1870s)
(womens' rights protest song)
Typical Girls - The Slits
(not a war protest song, but a feminist song)
Sister Suffragette - from the Disney movie "Mary Poppins"
(womens' rights protest song)
