Many sites speak against Islam and its prophet, many of them speak against the Koran and its teachings. No demonstrations have gone all out against them. They hold a POV that is not acceptable to Muslims, but that's fine. Many of them even attempt to do research about the topic they talk about to prove their POVs. The question is, would you consider someone who creates a film portraying Jesus or Mohammad as a child molester or as a fraud as someone practicing free speech? I think there is quite a difference between the two.
