When a Christian tries to evangelize you.
Look at them, smile with the compassion they have beneath their guise of ego, know that their intentions are good even if their ideas are disgusting and horrible. Then respond calmly with "I do love Jesus, but not as a unique son of god, how does god exist independent of his manifestation? But rather, as my equal, worship and condemnation are two sides of the same coin. As soon as I worship something outside of me, I condemn something inside of me, and others outside of me. It is a basic principle of philosophy, there is no space between cause and effect. You cannot be running to something without running from something else. Furthermore - you are not punished for your sin, you are punished BY your sin, so if I want to avoid punishment for my sin, I should simply stop sinning.
though the semantics of this argument may be in conflict with your ideas, beneath the differences seperated by semantics lies an inherent understanding to this. "Sin" to them, is the same thing as hostility, contempt, resentment, bitterness, and anger to you.
