I have a hard time believing Christians are under attack in America. Mostly because they're so totally not. Usually, when Christian groups are upset, it's not because their rights are being violated, but because they're no longer getting the privileged treatment they're used to receiving. So you should always take their complaints with a grain of salt and search for whatever they're not telling you.
