Whether or not Nakoula has purposely attempted to show that the Muslims are stupid, his "innocent" approach has brought the other subtle "innocence" side of the Muslims. You see, "innocence" also means "pure" in some unsophisticated way. What this episode suggests is that the Muslims' love to their Prophet is pure, irrespective whether they really follow his teachings or otherwise. In one brief period, all observant and non-observant Muslims were united in showing their anger to those who have insulted their Prophet.
This kind of approach is always counter productive. We have seen it many times already. Every time the Prophet is insulted, the Muslims would strongly protest in unison. Even those Muslims who have paid little attention to Islam in their daily lives rise to the occasion. In that sense, we can say that Nakoula's approach shows only his "innocent," read naive and plain stupid, in dealing with the matter.
The not so "innocence" way is the subtle approach by the Orientalists. Hiding behind scientific and scholarly works, these people have, to a large extent, succeeded in desanctifying Islamic Scripture and secularized Islamic Law. They have gained many adherents among the "innocence" Muslims who thought that they are sophisticated.
For that reason, I am not concerned with the "innocence" work such as the movie "Innocence of Muslims." Because it is too sickening, even the non-Muslims are embarrassed with it, as signified by the response made by Hillary Clinton, the US Secretary of State. My concern is the subtle works made by the Orientalists. Through their white magic, many Muslims have "innocently" fallen into their traps, as we have seen in al Mu'awwidhatayn.
