Freedom of speech?

Last week a well known film producer in my country was murdered, in broad daylight. He was cycling home when a muslim extremist overtook him and shot him to death. Why? Because the producer gave his personal opinion about some aspects of the islam. He said that the women are treated very badly in most muslim countries, and he even made a short film about it. This and this alone was the reason he was killed. Where does humanity stand if we can't even say what we think anymore? I thought we got through the middle ages already. Apparently not. Don't get me wrong, I'm not against the islam. I actually think that the islam has some really good concepts and ideas about certain things. What I am against is muslim extremism. Why can't you just accept non-muslim people's ideas? Why do you care what they say? Do you think that after performing actions like these that other non-muslims will quickly convert to islam? Think again. And the worst part of all; When the media report about these extremists, they don't want to be recognised. On video tapes they wear masks, in newspapers they don't want their name to be mentioned, and no pictures can be posted of them. If you have such extreme ideas, at least have the balls to openly come forward with them towards the whole world, without still hiding yourself. Weak is what I call these people. Weak in its most extreme form.
