The organization is calling on people to take a picture of themselves with a sign that says, “You can’t stomp on me,” and then upload the picture to the site. “By uploading your picture,” reads the e-mail, “you can show that your voice will not be silenced even in the face of intimidating and thuggish behavior. We’ll put all the photos in one public place as a statement of solidarity with Lauren and a promise to keep speaking out.”
