From this thread http://www.freerepublic.com/focus/f-news/1419001/posts comes this:
"Permitting a group to fly their flag from the Bridge of Lions enables that group to say 'We exist and this is what we stand for,'" said Karen Doering, staff attorney with the National Center for Lesbian Rights. "By denying this application, these city administrators are denying my clients their constitutionally guaranteed rights to freedom of speech and equal access under the law. That violates the First and Fourteenth Amendments."
Why would't the same apply to the Confederate flag
