In those days parents could let kids watch TV or read a book without having to be there with a moral interpretation
Was there witchcraft in alot of the childhood stories yea..but not as blatent as with Potter.It is sort of like TV...the decline has been so gradual that alot of the sheeple haven't got it yet.
This is a battle for the mind and heart of your kids..eithor fight it or lose it..your choice!
