It is true that the US is a freedom country that everyone can speak for him/herself. However, insults on a sacred of a religion is to make enemy of its believers and followers.
The thought of blood terrorism is caused by the X represented in the formula BT-X=Man by a whiteman guised as the doctor in the microfilm.Therefore, the film tries to ruin the image of X to describe him as the evil of killing,murder,robbery,adultery,whatever the dirtiest things in the world.
And the X in the film is the God of Muslin!
What can you expect the feelings and actions of Muslin???
