You're looking at it complete wrong. A copyright holder has the sole right to alter the material. A good example would be Ann Coulter's books.
Should I be able to sell edited copies of her books that take out the insults as long as I pay her royalties? No, of course not. Ann or or her publisher holds a copyright and that copyright gives them all the power over the work. I can't alter her works without her permission or the permission of whoever she's sold that authority to.
There is no reason at all why this should apply differently to movies. None at all. You might not like the language or nudity in a movie, but you can't alter it without the permission of whoever owns the copyright.
I really think that cleaning up a pile of poop left by the liberal "artists" is beyond any filtering anyway. I just wish Christians just completely avoided their trash instead of trying to trying to stomach it with a grain of salt. Deep down they know that all the trash you put in your mind builds up a tolerance to such smut. I am glad I still grit my teeth every time I hear the "F" bomb. It makes my blood boil to hear people lower something perfect God made in his perfect surrounding of marriage into just a matter of trash. God knew what he was doing when he made something so beautiful as woman... but now days that beauty has been dragged Thu the mud to where it is ugly as the words they use to describe it. Only libs could do such a thing to the most beautiful thing God created (other than His Son and His Word)...
Your words ring true.. but the filters I put on information coming into my head change the basic points into what I stated as the truth as I see it. "Let love be without hypocrisy. Abhor what is evil" (Rom. 12:9) A love that is not hypocritical rebukes and condemns, and then points the way to God.
Now on the other hand, God does not condone stealing either, is stealing the smut out of movies "stealing"... I guess the courts and you are right, it is stealing.. since the poop pushing "artists" claim ownership of it with pride.
So as I previously stated.. the best I could hope for is that Christians stop purchasing/renting from porn/dirt peddling artists. Even the cleaned version resulted in those "artists" getting paid. Even movies that add just a curse word here and there is not good enough in my opinion.. If a person makes some brownies with all good wholesome ingredients and just puts a sprinkle of poop in the mix, the whole of the mix/movie has been compromised.
