Are you arguing that God does not hate sorcery and homosexual acts, that God does not consider fornication or adultery to be sinful, or are you saying you do not believe God cares whether we are entertained by sin, or what?
In the past I have used incantations, spells. Various incantions/spells muttered in horror and sci-fi fiction may be different incantations, may be different in various ways, ok. Regardless, using incantations, muttering spells, is condemned in Scripture. I don't see any good thing in being entertained by sin, I don't see any good in being entertained by the training of sorcerers as to how to harness their powers by muttering incantatons/spells.
If I may...
LinuxUser has already addressed repeatedly that there is no problem with your personal convictions about being entertained by things you perceive as sin.
The problem arrises when you universalize your convictions to apply to everyone else.
It is when you (or any of us) take something we are personally convicted about and say it is wrong for everyone to do.
I, too, am okay with you not exposing yourself to forms of entertainment based on personal conviction.
However, I too agree with LinuxUser that it is inappropriate to universalize your personal convictions on this matter.
I believe that Paul, when he wrote Romans 14, had a situation very much like this one in mind. Sure, in the specific context of his letter, the matter revolved around diet. But, the principle is still the same.
You are convinced that doing something is a sin, so you shouldn't do it, because for you, it is a sin. However, to those who are okay doing it, it is okay for them to do, just so long as them doing it is not a stumbling block for you.
The reason I believe the principle is communicable to this issue is because the dietary argument was that the Scriptures called eating those foods a sin, and yet there were Christians eating those foods and sure that they weren't sinning. Debates like this one sprouted up, and those Christians who were once confident they were not sinning now weren't so sure. Those arguing that they were sinning were creating confusion and guilt where there was no need. So, Paul wrote this part of the letter to restore confidence to those who did not believe they were sinning.
Likewise, I believe LinuxUser is continuing to discuss this matter with you because he is sure, in agreement with you, that it is not okay for you to view these things as entertainment, but is also sure, in contrast to some of your arguments, that it is also totally okay for others to view these things as entertainment.
As Paul writes in Romans 14:14, "I am convinced, being fully persuaded in the Lord Jesus, that nothing is unclean in itself. But if anyone regards something as unclean, then for that person it is unclean."
I believe this is true.
