Nobody, but you seem to be legitimizing their response as merely "offense", denigrating those who draw Muhammed by saying that they should expect a "tiger" to bite, and dismissing any argument about "freedom of speech" as being "islamophobic".
Guess what? It's not. It's what people in a civilized society do - they permit other people freedom and don't think that they should deserve death because of it. And when people exist who do believe that others deserve to be killed just because of what they believe or how they choose to express it, we rightly condemn those people and accuse them of being barbaric, evil or sick. So far, all you've really done is make excuses for such people. I'm not saying you agree with them, but your incapability to admit that there is anything disproportionate, wrong or inherently psychotic about such a response.
If you want people to understand (as some of us on here do) that such a response is not universal for the Muslim community, then you have a duty to stand side-by-side with those of us who condemn such hyperbolic responses as barbaric, and instead you should be engaging in reasonable discussion on the subject. That's what people in a civilized society should do.
Well, do you think I would be justified in threatening murder on those who impose on freedom of speech? If I carried out such a threat, would you call my response "offense" and call those who I murder (or intent to murder) people who just "got bitten by a tiger"?
