From that site:
“Because we have and love our own Gods, Wiccans have nothing to do with other people’s deities or devils, like the Christian God or Satan, the Muslim Allah or the Jewish Jehovah (reputedly not his real name). Christians often deny this fact because they think that their particular god is the only God, and everybody else in the whole world must be worshipping their devil. How arrogant.
They’re wrong on both counts. “
