Deborah,
Folk music by definition is a product of it's time - a product of people living in that time. Thankfully, current folk music, however you want to define it, has a strong current of gender awareness.
But, historically, when the times were sexist, the music of the people was sexist. When times were racist, the music of the people was racist.
If your looking for songs that are pure, from the feminist perspective, historical folk music is a bad place to look. There are a few great ones, but the alpha male vision predominates. If you are looking for songs that promote a feminist vision, current folk music is an excellent place to look.
If you go up to the top of the forum page, you will see a Search Engine for searching the Digital Tradition Data Base. Type @feminist in the block and press go. You will get over 50 "feminist" songs. Some are historical, but many are new.
Good luck!
