well unless your statement
Look at it this way, ITACHI OWNED KURENAI TO HELL WITHOUT USING STUPID MANGEKYOU
was just thrown in randomly it would apear to be a swipe taken at the fact that a jounin ANT jounin could defeat itachi. but of course he OWNED kurenai, because she was using a technique he was strong against. where as perhaps if she used someting he was weak against then it may not have been 100% one sided.
