Members of the Zioness initiative, which launched Tuesday, will march together on Saturday at SlutWalk Chicago, a women’s rights demonstration against sexual violence. Zioness members will be marching with banners and T-shirts featuring a design of a woman wearing a Star of David necklace. Organizers of the SlutWalk initially said that they would ban Stars of David from the event, but later altered their policy to allow religious symbols but not national flags.
