Yup, this is why theology classes lead by professional theologians and apologists need to be implemented before some one picks up the Bible and reads it based on his understandings.
The Bible teaches that we are to study to show ourselves approved unto God.
"Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth." (2 Timothy 2:15).
The Bereans were more noble because they checked the spoken Word of God to see if it lined up with the Scriptures.
"These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so." (Acts of the Apostles 17:11).
John said to the brethren he was writing to that they had no need that any man to teach them because they had an anointing that abided in them to teach them all things.
"But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him." (1 John 2:27).
People do not understand today because they justify sin or ungodliness.
3 "If any man teach otherwise, and consent not to wholesome words,
even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness;
4 He is proud, knowing nothing,..." (1 Timothy 6:3-4).
People do not understand today because they don't ask God for the understanding.
"Call unto me, and I will answer thee, and shew thee great and mighty things, which thou knowest not." (Jeremiah 33:3).
Here's to explain the necessity with God's test to Abraham
Why did God tell Abraham to sacrifice Isaac?
Yes, I have known for many years now that Abraham knew that God was going to resurrect his son (i.e. Hebrews 11:17-19), and thus GOD was not asking Abraham to permanently take the life of his son. I just recently mentioned this fact within this thread before having read your post.
Note: I chose to read and reply to your post last because I was replying to the most recent posts first and working my way backwards. Hence, why I posted Hebrews 11:17-19 without having read your post yet. In short, your not telling me anything that I did not already know. But your failing to realize that GOD was still asking to take the life of his son. Abraham still had to trust by faith that GOD was going to resurrect his son, as well. Abraham was being asked to take the life of his son (Which is like taking out one's eye, or the cutting off one's hand). Of course, I recently mentioned that taking one's eye, or cutting off one's hand should be the ultimate last resort when a believer has exhausted all other possibilities with GOD. Most are not going to want to chop off their hand, and eye (even in such cases). So it pushes a person to want to seek some other way to cut sin out of their lives.

Sure. I will not argue that any form of content can influence someone negatively,
This is what you are arguing against, though.
You don't think that sinful secular movies do not lead people to do sinful things from watching sinful movies. I can testify of having seen others sin as a result of these movies, etc.
You said:
but that goes for everything; even christian related content can influence someone negatively - we have Televangelists, shows in where you need to vow your faith through $1k, churches with "xyz is going to hell". These examples have caused more to leave Christianity than the fantasy entertainment that has been mentioned here.
A person who has not been born again spiritually and who does not have the root of righteousness within them is going to fall away in such cases. Christians who leave Christianity over minor things like false Televangelists, or false professing believers doing wrong things have not really met the two necessary conditions as a part of being a true Christian. Yes, sin can still destroy a Christian, but Televangelists are not going to make a true believer to depart from the living God. It would be the deceitfulness of sin that will harden their heart that will do that.

I additionally consider this thread as an example because seeing that we have grown adults being that incapable of comprehending something so basic as the concept of fiction -- or can't even tell when something so obvious isn't real, then you have been badly influenced over bad theology.
Again, a person cannot change the reality of sin in piece of fictional work that they create. A man can write a book and say that the sin of inappropriate content does not exist in his universe or world within his book, but that does not change the reality of such a sin; Anymore than a person who writes about the sin of witchcraft and declares it to be okay and acceptable within their universe. You somehow think that just because a movie, or book is fantasy that the sins being depicted within them are not real sins being pushed upon the one who partakes of that form of entertainment. No man can change the reality of sin with fiction or fantasy. Sin is still real within their fictional works, and they have influenced people to do sinful things that these fictional works promoted.
Also, when a person watches a movie, or reads a book that is fictional, they don't say to themselves repeatedly, "This is fake, this is fake, this is fake." etc. If they were to do that they could not enjoy the book or movie. They watch these movies and read these books pretending that they are real on some level because most people get emotional over partaking of these fictional works. They cry, laugh, get sad, etc. It effects them on an emotional level. So they must think it is real on some level while they are watching it so as to enjoy it. They must pretend it is real, and thus when the sins are being pushed upon them when they are enjoying this make believe world that they are pretending is real for a time, they can be influenced to sin in the real world. They will take from these movies the things that are within them. Christians even try to apply the good that are within sinful secular movies. They try to apply these movies to their life. They make them to be these great things to follow, when in reality, they also promote sin upon them. They have to turn a blind eye to these sinful things in order to enjoy it.

I find it strange how some here talk about OSAS, "God is great", "we are never taken away from his hand" yet we have to take extreme caution against Hermione.
I am strongly against OSAS (Once Saved Always Saved) or Belief Alone-ism.
I am a Trinitarian Sola Scriptura Christian who believes that the salvation equation is:
"Faith + Works of Faith = Salvation."
1 John 2:15-17 is a passage you should meditate on and study, and pray to the Lord about. I know that if you were to make it your life mission to know what it says plainly and to believe it, you will come to the conclusion of putting away secular sinful movies, books, etc. out of your life and encourage others to do so, as well.
