Unfortunately, the terms get confused, and thus dudes get confused over who is who and what is what.
To summarize we have the following:
Neopagans: those who follow a modern version of an old pagan faith, such as the Celtic faith. Some call themself 'witches". Sometimes “shamanists”. A legit faith.
Wiccans: a more or less new faith, with some ties to “neo-paganism” and borrowing some traditions from the old pagan faiths, and some symbolism & terms from Witchcraft & Satanism. Some Wiccans call themselves “witches”. Also legit- altho there are “poseurs” of course.
Witches- traditionally; someone who barters with the nether powers, that is demons & devils and spirits, thus a “satanist” in a way. However, for some odd reason, Wiccans & some Neo-pagans insist on calling themselves “witches”, then get all upset when dudes confuse them with sorcerers/witches/satanists. Not a “real” religion- IMHO. However, those that are “wiccans” but call themselves “witches” are in a “real faith”, of course (see above).
(If you really NEED to be called a “witch” then fine- but do not get all huffy when dudes get you confused with the traditional meaning of the word. Why not come up with a new word, rather than trying to change the meaning of a word loaded with so much negative connotation? Note that “rabbi” means “teacher”, and thus one could call themself “rabbi” if one “taught” a faith or religous philosphy. But then- if you did so- don’t get all riled if dudes think you are Jewish, please)
Pagans- those who follow “old school” non-bibilical faiths. The american Indian faiths are “pagans”. Their preists can be called “shamans”. Very real.
Satanists: those who worship the Adversary, Lucifer, the Prince of Darkness, etc. Some call themselves “witches”. Can legitimately be assumed to be “not nice”. Some deluded crazies do horrible things in the name of “satanism”- however, there is no evidence they are organized in any way. Real?
The “Church of Satan”: a modern re-doing of “Satanism” by Levay & co. Not the only “satanists” in the world. More “egoists” than “evil”. I am not sure if these guys take themselves seriously.
I admit there is exactly no evidence that “satanists” commited this murder. Which is exactly equal to the amount of evidence (that has been released) that Scott did it. Maybe that is the point that the attorney is making.
