I was agreeing until this point. Scripture tells us to expose lies, particularly those of false teachers.
There's a saying, "The only thing necessary for the triumph of evil is that good men do nothing." It's actually biblical at its core. Jesus and the Apostles pointed out false teachings and lies often. It's an act of love.
Paul talked about the war on truth and the importances of exposing lies, even demolishing them.
2Cor. 10:3 For though we live in the world, we do not wage war as the world does. 4 The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. 5 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.
