The word "world" in James 4, refers to that system headed up by Satan and run by demons and evil humans to rebel against God, and leave God out of their lives.
Think about what God says in the Bible about loving Him with out total person, and loving our neighbor as ourselves as the greatest commandments respectively (Mark 12:28-33). Think about what God says about marriage between a man and a woman (Gen 2:24-25), drunkenness, sexual immorality of all sorts, idol worship, stealing, cheating, etc. (I Cor. 6:9) and other passages that describe what God's expects from His Children.
God says that if we befriend the worlds principles and hangout with the worlds principles, and practice what the world is doing versus what He expects, we are on the wrong side.
Popular demand and "what everyone else is doing" is no excuse for a Christian.
We are on God's side or we are on the devils side via worldly living. Look at James 4:4:
4 You adulteresses, do you not know that friendship with the world is hostility toward God? Therefore whoever wishes to be a friend of the world makes himself an enemy of God.
Christians, let us take a clear stand on God's side. People should not guess where we stand on issues clearly addressed in the Bible. Our light must shine bright and we must be salty so that non-believers become thirsty for the Living God and ask what they must do to get a personal relationship with God.
Be on the right side all day every day.
