Sorry, my friend but 1 John 4:1-3 is about the Gnostics who believed that Jesus came only in Spirit, therefore, any sins of the flesh, didn't count, only sins of their spirit. They even taught grace was to be proved by raping each other's wives every day. That was the sin of the Nicolaitans. This also explains 1 John 1:6, 8 and 10. They didn't believe their sins of darkness in the flesh were not sins at all. But they were in the church spreading false doctrine. Another reason for John to use "we." John didn't mean that applied to everyone in the church as is another false doctrine, but not one you hold to nor I, but Calvinists do, and most with western literal thinking. They are known for taking verses out of context, and standing on one verse instead of the whole Word of God.
But you know this already. Those are not Trinitarians and you know it. Nice try, though hysterical. Thanks for the good laugh.
