Problem #1 You went in there to make them see sense? Really? So basically you went into "save" them right? That's not our job or even an obtainable goal. We are to speak the truth in love, and the Holy Spirit does the rest. We do not have the power to change anyone's heart or mind regarding the things of God. It is a foolish waste of time that generally results in deepening the resentment already felt towards Christians, Christianity, and religion.
Problem #2 Your attitude. There is a stench coming from your post because of the self-righteousness it contains. How dare you talk down to or about someone who doesn't agree with your beliefs and then turn around and call yourself a Christian! That kind of haughtiness is no representation of Christ, God, or the bible. It is a complete and perfect representation of a religious spirit.
