We can't have prayer in schools because they may be offended. We're entitled to our rights too. Extending civil rights to one sector of society does not withdraw rights from another. Most civil rights ordinances provide exemptions for religious institutions. We don't want our own forms of prayer in schools either.
Earth based religions want to be treated like a minority, like an ethnic minority.
The Supreme Court says they're not. There were no confirmed large scale incidents against minority religions advanced to allow the RFRA to stand. That was main reason that the RFRA was declared invalid. Witches and Pagans are a numerical minority in American society. Like ethnic minorities, we do face job loss, eviction and the loss of our children simply because of who we are.
