I think Hirsi Ali is a very intelligent and creative person, but the movie should not have been promoted as road to better the situations of some muslima. I rather think of it as a therapeutic tool for Hirsi Ali then a bridge to reach muslim women in the Netherlands.
I do, however, think that it was the intent of Submission to better the situation of muslim women - starting in western cultures. Hirsi Ali has been forthright about her intentions from the first day. I think, though, that the effects of the movie are nill - not many muslim women were reached or affected, it just polarized the debate.
So, my view in brief, it shouldn't have been promoted as a bridge to reach muslim women, yet it was, but it didn't really work.
