If you are sinning and you don't know you are sinning is it a sin?

Unless one is psychotic then they wouldn't know what sin is or care, but if one isn't then they know deep down they are guilty of a sin even if they don't try to rectify it. When the missionaries went to pre-USA-Hawaii, they were aghast by King Kamehameha's adulterous relationship with his subjects; there were about 19 different Hawaiian sex-practices that were considered adulterous by the Christian missionaries. The missionaries then warned the King that if he did not stop practicing this Sin of adultery, the God will be angry at him and punish him with eternal damnation in hell. King Kamehameha retorted; "What do you mean god will be angry and punish me? I am God!" Moral; what is SIN to some may not be SIN to others... Learn this story from the book "Hawaii" by; James Michener.. The concept of "sin" is a religious construct. If one is not religious, then "sin," as such, does not exist for that particular individual.
