Nah. You gotta be polite for the whole thing just like this guy, but then you have to add a one-word paragraph at the end just containing "cunt", no caps or punctuation. Just "cunt" at the end. Just as a little sort of "fuck you I was polite and didn't have to be so now that I've fulfilled my unnecessary obligation to school the fuck out of you here's a little fuck you in return".
Ending it by causing insult in such an uncreative obvious way is unbefitting of the original eloquence. A better conclusion would be, instead of simply cursing/insulting, fitting an individualized accurate mild to moderately insulting descriptor/instruction as was done in the post.
