16 years ago in response to what she perceived as the moral and intellectual laxity among many feminist commentators"), about how the Harry Potter phenomenon is "definitely draw[ing] kids to witchcraft" which included (without intended irony) the following quote straight out of The Onion's parody:
High Priest Egan of The First Church of Satan in Salem, Mass., celebrates Harry's contribution, saying, "Harry is an absolute godsend . . . we've had more applicants than we can handle lately."
Apparently the obvious humor of a High Priest of the First Church of Satan's calling the arrival of the Harry Potter phenomenon a "godsend" went right over more than a few people's heads. (The Onion's quote has since been excised from the WorldNetDaily version of this article, but it still appears in the original from Creators Syndicate).

Those determined to demonstrate that the Harry Potter's popularity is an evil influence on children incredibly maintain that even if The Onion piece is parody, it nonetheless accurately reflects author J.K. Rowling's attitudes and a real-life phenomenon of a massive recruitment of children by "satanic cults." Everything here is bogus, from the phony quotes attributed to Harry Potter author J.K. Rowling (from The Onion) to the ludicrous "statistics" about "open applicants to Satan worship having increased from around 100,000 to now . . . 20 MILLION" (from whoever penned the e-mail rant).

As the Associated Press reported:
Scottish author J.K. Rowling calls the accusations "absurd," saying Harry Potter's world is entirely imaginary.

"I have met thousands of children now, and not even one time has a child come up to me and said, 'Ms. Rowling, I'm so glad I've read these books because now I want to be a witch,'" the author has said.

Though more than 50 million copies are in print worldwide, there has been no evidence of widespread conversions to paganism or witchcraft.
As to the issue of hordes of children willingly flocking to join "satanic cults," this concept is ably debunked at length in Jeffrey S. Victor's 1993 book, Satanic Panic: The Making of a Contemporary Legend. We can't summarize his lengthy analysis in a single paragraph, but the introduction offers a good overview of his thesis:
Again and again we are told — by journalists, police, and fundamentalists — that there exists a secret network of criminal fanatics, worshippers of Satan, who are responsible for kidnapping, human sacrifice, sexual abuse and torture of children, drug-dealing, mutilation of animals, desecration of churches and cemeteries, pornography, heavy metal lyrics, and cannibalism.

This popular tale is almost entirely without foundation, but the legend continues to gather momentum, in the teeth of evidence and good sense. Networks of 'child advocates', credulous or self-serving social workers, instant-expert police officers, and unscrupulous ministers of religion help to spread the panic, along with fabricated survivors' memoirs passed off as true accounts, and irresponsible broadcast 'investigations'. A classic witch-hunt, comparable to those of medieval Europe, is under way. Innocent victims are smeared and railroaded.

Satanic Panic uncovers the truth behind the satanic cult hysteria, and exposes the roots of this malignant mythology, showing in detail how unsubstantiated rumor becomes transformed into publicly-accepted 'fact'.
If The Onion's parody has demonstrated anything, it's that we should be worrying about adults not being able to distinguish between fiction and reality. The kids themselves seem to have a pretty good grasp of it.
