Wicca is as legitimate a religion as any, but that's hardly a reason for non-believers to worry that Wiccans might utter incantations or cast spells that actually harm others, or successfully "raise spirits" or "call up dark forces". I have to wonder what sort of wacky beliefs the university authorities hold, that makes them think it's necessary to put these restrictions on campus Wiccan practices.
In fact, precious few Wiccans even believe they can "raise spirits" or "call up dark forces". And harming others via spells or incantations (which many Wiccans don't believe is possible, but some do) is prohibited by the Wiccan Rede "an' ye harm none, do what ye will", and most Wiccans believe that any harm they cause deliberately will come back at them multiplied threefold.
Catholicism.
well, maybe a wiccan spell done by an incompetent wiccan could inadvertently harm someone.
if i were a lawyer, i would be looking into this as a potentially profitable area of legal practice.
"HARMED BY WICCAN SPELLS?
