The National Organization for Women is celebrating Women’s Equality Day this year by launching Say It, Sister! — a new blog designed to inform, inspire and instigate feminist activism.

Women’s Equality Day marks the passage of the 19th Amendment to the U.S. Constitution, which guaranteed women the right to vote. For more than 70 years, the foremothers of feminism campaigned for women’s equality at the polls, and they finally achieved victory in 1920.

Nearly a century later, the ballot box remains vital to protecting and advancing women’s rights, but the way we educate voters and petition our government has changed dramatically. The Internet has brought us unprecedented organizing power, and there’s little doubt that suffragists like Susan B. Anthony, Elizabeth Cady Stanton and Sojourner Truth would have welcomed this tremendous opportunity to amplify their voices and reach out to women across the country and around the globe.

In the tradition of those great feminists, Say It, Sister! will bring women’s rights supporters together to motivate and strengthen each other in our mission to end all forms of sex discrimination. The blog will serve as a place where NOW leaders speak their minds, call women and men to action, encourage feedback and facilitate a lively dialogue.

“I am thrilled to launch NOW’s blog, Say It, Sister!, on Women’s Equality Day,” said NOW Action Vice President Erin Matson. “As Elizabeth Cady Stanton said so long ago, there are many hungry people out there. Well, now we have this incredible power to nourish them and point them in the right direction to make change, and that’s just what we plan to do!”
