Find a different threat or make your own.
Without a quote I can't even guess who she was talking about -- could be anybody. I'm assuming it refers to the OP. That would make sense.
Wicca use nature. Harm is not part of their practice or it rebounds on them three fold.
Perfectly expressed.
And, I suspect, completely over the OP's head.
30,000 feet over head
Okay, this is interesting. Who are the Wicca? And I can imagine that harm would rebound, but why do the others still do it? Do they think they can get away with it? But more importantly, does this mean that the harm disappears when they are killed?
Wiccans used to be accused of "witchcraft" and devil worship, but they simply have a deep understanding of nature to help other. They believe in a goddess, or mother nature, instead of a male figure. Rituals are part of the theurgy to draw energy from each other or from nature/mother earth.
Wiccan rede, a philosophy/creed, is more or less "do what you want, but harm none"
There are dark witches, but most are just want to bes playing at magic but not truly understanding.
More humanist than truly harmful.
