A few decades ago, one of my favorite posters was “Sisterhood is Blooming Springtime Will Never Be The Same” by the Chicago Women’s Liberation Union. It captured the excitement and optimism of the women’s movement at that time. I still smile when I think of it. Yet, I am distressed to see so many women who call themselves feminist ignore, support — and in cases of women in power, wage — war against other women all over the world. So I decided to borrow from this earlier poster to make a new statement on sisterhood.
