No.
I’m surprised this needs to be explained.
If I start shouting hateful, horrible words at your wife/husband (if you don’t have one pretend you do for sake of argument) will you stand there and shrug deeming it my right to free speech or will you take action to defend her/him?
We ALL have the right to say what we want (within some moderate restrictions such as slander). That does not mean we spout whatever goofy shit crosses our mind.
Words have power and have an effect and ignoring that to suggest because we can say whatever we want it is somehow ok to say whatever we want is short sighted in the extreme. I am willing to bet you self-censor yourself on a near daily basis and moderate what you say from what is actually on your mind.
Make no mistake, Muslims (some of them at least) need to get a thicker skin and be more tolerant. Their beliefs are not universally shared and they have no right to impose their restrictions on someone else who does not agree with them.
That said the movie in question (I have watched some of it) is not fair comment or parody or comedy or anything other than a poorly made hateful smear. OF COURSE it is going to piss people off!
Yes, Muslims should have looked at it and blown it off for the bullshit it is. In any population of millions you are bound to find someone who you intensely dislike. Killing others because they share nothing more than a nationality with that person is flat out retarded.
With that in mind the person making that film is aiming to incite and he succeeded. He got people killed as a result.
Words have consequences and that should be considered before you speak.
