A movie about homosexual life in the muslim community, being made by a cast of performers and film makers who will have to work annonymously in fear of their lives. Also a foreign film.

Trembling Before G-d is a five year old movie about gay hasidic Jews. It's also a French film.

MAROCK is a foreign film. I've never heard a thing about it. Even IMDB has no information regarding the story.

LOOKING FOR COMEDY IN THE MUSLIM WORLD is the only domestic film you mentioned, but it wasn't meant to be a critical movie of Islamism. And is still made the movies studios wet themself in fear. That's why it was released with virtually no press. Note, it's a year old.
I don't see how any of these films make your point. The Albert Brookes comedy might have, but it's the only domestic example you provided and the studios were reluctant to release it at the time. Furthermore, it's not a movie critical of Islam, it's more a movie mocking the Albert Brooke's character.
Nothing at all critical of the religion or foundations. No movie about Mohammed raping children or imaginary conspiracies undermining the credibility of the the Ayatollahs.
And the Theo Van Gogh movie that incited his murder was called "Submission." It was a 10 minute film about the abuse of women in muslim society.
