Religious Freedom?

For those who don't know it, I am a Pagan,Wiccan or just plain Witch if you prefer. I recently attended a festival called Pagan Unity Days here.(Charleston,S.C.) I am also a photographer and was asked to take pictures for the website. But I had to be careful as not all my fellow Pagans are out of the broom closet. Some hid their faces and others just asked that I not take their picture for fear of being outed at work. Now what the laws say and actual practice are two different things as we all know. But in this day and age why do people of any faith need to hide? Why are we still debating the First Amendment? Religious Freedom is just that, not for one faith but for all.
