Does it violate a clear Scriptural principle?
Thou art of purer eyes than to behold evil, and canst not look on iniquity: wherefore lookest thou upon them that deal treacherously, and holdest thy tongue when the wicked devoureth the man that is more righteous than he? (Habakkuk 1:13)
This should "go without saying," as the old saying goes. In reality, this question finds rare application in many professing Christian homes today. Think about it: if God hates lying, drunkenness, adultery, murder, fornication, sodomy, stealing, idolatry, lust, violence, and covetousness, not setting it before His eyes, why would He find pleasure in you setting it before your eyes, or in your mind, or wilfully filling your ears with it, or allowing that sort of joking on your lips? The verse above is part of a question made by the prophet Habakkuk who understood God's holiness and questioned Him as to why He allowed the wicked to carry on in their wickedness before His eyes. The answer that follows throughout the book is that God is merciful, although judgment will come. It is evident throughout the book, though, that God's mercy in withholding judgment for the wickedness of the nation was not due to His being entertained by it!
