From a netfriend:

Just as a small sample, imagine a ten-year-old reading about

1.The animal sacrifice of a cat[19] 19 Harry Potter and the Chamber of Secrets, p. 139.

2.Non-magicians like you and I (Muggles) are portrayed as dull, boring, cruel or useless;[20] Harry Potter and the Goblet of Fire, p. 33.

3.Power is the ultimate moral choice, irrespective of good or evil;[21] Harry Potter and the Philosopher’s Stone, p. 29

4.Blood sacrifices;[22] Harry Potter and the Philosopher’s Stone, p. 656.

5.Cutting off the hand of a living person for a ritual;[23] Ibid. p. 641.

6.Boiling what seems to be a baby or fetus alive in a cauldron;[24] Goblet of Fire, p.666. Careful reading of this passage does reveal that the fetus-like creature which is thrown into the cauldron is actually Lord Voldemort. However, many younger children may not get this point (we didn’t at first) and it is still an extremely disturbing image.

7.Possible demon possession;[25] Goblet of Fire, p. 653-54.

8.Werewolves [26] & vampires [27] Ibid., p.147.28 Harry Potter and the Goblet of Fire, p. 463.

9.Bringing a evil wizard back from the dead through the shedding of blood [28] Harry Potter and the Goblet of Fire, p. 463.

10.Astral project or travel [29] Ibid., pp. 667-669.

11.Casting spells and levitation [30] Ibid., pp. 344-45.

12.Being able to shape-shift into an animal [31] Ibid., p. 534.

13.Crystal gazing or divination [32] Harry Potter and the Prisoner of Azkaban, p. 29

14.A hero (Harry) who tells lies, [33] steals, [34] breaks the rules,[35] and cheats by copying another student’s homework,[36]

(cheating is OK in wizard ethics[37]). 34 Harry Potter and the Chamber of Secrets, p. 165.35 Prisoner of Azkaban, p.31. 36Ibid., p. 146. 37Goblet of Fire, p. 343Approval of astrology[38]

15.Being taught that people can exist without their souls[39]

Prisoner of Azkaban, p. 247.

16.Communion with the dead, dead souls living within us[40] Ibid., 427-428

17.Harry takes mood-altering drugs (which are REAL herbs that are used by witches and shamans)[41] Sorcerer’s Stone, p. 137, 286-87.

18.Use of the “Hand of Glory,”[42] a grisly occult artifact that is the severed hand of a hanged murderer. Its fingers are lit and burned as candles. The hand is placed in a house to make everyone in the house fall into a spell [42]Prisoner of Azkaban, p. 52.

19.Use of magic charms[43] Ibid., p.118, 188.

20.Belief that death is just the “next great adventure”[44] (which might be true if you were a Christian, but no one in these books is a professing Christian.) For non-Christians like Harry, death is a one-way ticket to hell![44] Sorcerer’s Stone, p. 302.
