I will only say this about Harry Potter,it is dangerous for this reason.
The Bible warns us of the new age movement interpretation of the Bible,based on the occult,that will become so popular that people will only want to hear it according to that interpretation,which the new age movement will unify the religions,with a false interpretation of all religions not compatible,which is about harnessing the power of nature,spiritual enlightenment.
Jesus said that since iniquity shall abound the love of many shall grow cold,and people like to exalt themselves highly when they do not like each others feelings.
The last generation highly selfish,highly arrogant,want to heap money to themselves,and devour the poor from off the earth,and the needy among men.
Man of sin in to witchcraft,the occult,acknowledges no god,but honors the God of forces,the force of nature.
Evil men shall wax worse and worse,deceiving,and being deceived.
Comic book characters with their super ability.
Everybody wants to exalt themselves,and no one wants to be left out.
But not all can exalt themselves with money,and material things,and physical excellence,and intelligence.
So the new age movement,which is the future anyway,will appeal to the people that cannot exalt them self any other way,and the new age movement will be pushed big time.
It is dangerous because they show a kid that is not all that great in the physical power department,but when it comes to the power of nature,he has power to overcome foes bigger,and greater than him.
That will influence a lot of people that otherwise cannot exalt themselves,and the new age movement,harnessing the power of nature for power,will be the religion of the future,as they will not want to hear the truth of the Bible,but according to the new age movement,harnessing the power of nature,which does not matter if you weigh 300 lbs. in the strong man competition,with the fighting skills of Bruce Lee,or a 90 lbs. pencil neck geek,by nature it does not matter.
It will appeal to all the wimpy,geeky,want to be tough people,that cannot exalt themselves any other way,and to say I too am special.
Like Pokemon,Magic the gathering,and all the occult things they have in society,to get them interested in things of the occult,and when the new age movement comes to power,away they go,for now they have a way to exalt themselves in a world where they are basically considered a nobody,and they say screw you,for I am somebody now.
For everybody wants to exalt themselves,and nobody wants to be left out,and Harry Power will cause them to think I too can be somebody important,despite the odds against me if I apply myself by nature.
