I have done nothing but try to help you not commit copyright infringement (a crime). Please do not insult me that I am "fuming" and "so mad", it's degrading. Especially given that the context is that I have been trying to save you from getting into legal trouble and trying to help you learn the etiquette of what images you may use as your avatar. To be clear, your avatar should not contain a character or art does not belong to you (examples: a picture of a fursuit you do not own, a company mascot, a furry picture that you did not commission or draw).
I do however accept your apology, I believe your error is that you are young and simply ignorant of these facts.
