BBC3 channel is airing a documentary (that is questionably just another ruse of a “reality” show) called Teen Exorcists about these girls that are, well, exorcists. From BBC3:
They are young, all-American girls who enjoy horse riding, karate and Sherlock Holmes. But there’s more to Brynne, Tess and Savannah three than wholesome pursuits – they’re exorcists.
Here’s another website with more about the show (more so than the BBC3 website itself). Mirror.co:
They came to “kick some demon butt” because they fear we’ve been corrupted by Harry Potter, whose spells they think are REAL.
The girls say they are “horrified by the sense of evil” engulfing the UK, with Savannah warning: “The people of England are under such heavy attack by the enemy.”
But if their claims spark scorn from sceptics, their mentor – Brynne’s dad Bob, a TV evangelist – prompts fears of a rip-off.
For Rev Bob, who was once filmed exorcising a “homosexual sex demon” from a man, packs his website with merchandise offers and pay-for services including a test to find out if you have the Devil or his minions in you.
Another angle from which the television attacks is the cartoons shown to children. Similar to the advertising ploy to attract children as young as possible to make them lifelong customers, the industry uses cartoons to convey messages to these impressionable minds. Depending on how deep down the rabbit hole you want to go, it even uses children to perform magic rituals through their imagination. The children will reenact magic spells they see on films like Harry Potter and supposedly these spells are doing real damage in an ethereal sense. I wrote up an extensive analysis of the 1980’s cartoon series He-man and the Masters of the Universe that conveys the occult symbolism and purpose for it. This example is the best way to explain how the system works and you can read it in the Appendix.
Here’s another piece of insight into this from ChristianAnswers:
As one example among many, Caryl points to a chapter in the fourth book entitled Flesh, Blood and Bone.
“Harry is magically transported with his friend Cedric to a dark, scary graveyard. There, Harry is tied to the headstone of Lord Voldemort’s father’s tomb by Voldemort’s slave, Wormtail—a shapeshifter who takes the form of a rat. A slithering snake, synonymous with the presence of Voldemort, circles around Harry. Following an order to kill from a voice of unknown origin, the slave utters a death curse. In shock, Harry witnesses the murder of his friend Cedric.” 
Perhaps all of this sounds a bit scary, but nothing to be concerned about. Potter fans say that this world is just make-believe and has no bearing on the real world. While a few Christians don’t even like to read or see classics such as Sleeping Beauty, Lord of the Rings, or Chronicles of Narnia due to the mere presence of evil, most Christians recognize the good vs. evil element as being clearly delineated. Evil is evil, and good is good, and good is promoted while evil is not.
But in the Potter series, the line is not so clear. The “good” guys practice “white magic”, while the bad guys practice the “Dark Arts”. Readers become fascinated with the magic used (explained in remarkable detail). Yet God is clear in Scripture that any practice of magic is an “abomination” to him. God doesn’t distinguish between “white” and “dark” magic since they both originate from the same source.
“There shall not be found among you anyone who …practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead. For all who do these things are an abomination to the LORD, and because of these abominations the LORD your God drives them out from before you. You shall be blameless before the LORD your God. For these nations which you will dispossess listened to soothsayers and diviners; but as for you, the LORD your God has not appointed such for you.”- Deut. 18:10-14
Here’s yet another website (that I won’t copy/paste from; it’s far too long), where the person claims to be a former witch, you can judge it for yourselves: https://www.pacinst.com/witch.htm
