The common analogy is that singling out Muslim fanatics as representational of the faith is like making assumptions about Christianity based on what you know about the Ku Klux Klan. This is essentially correct in tone, but not in degree. The KKK does not influence entire countries, nor do they approach nuclear capability.
The problem is even simpler than trying to figure out who gets to decide what is "offensive". It's getting these lunatics to understand what the appropriate response is to being insulted, that not every slight is an excuse to go off the rails. You'd think that it would have lost some its piss even for them by now, seeing as how they outraged by mundane items such as editorial cartoons and opinion columns.
But that's what makes them fanatics -- they don't listen to reason in the first place. It is then the responsibility of rational people -- in this case, the craven act of a supposedly democratic government arresting the editor and publisher of a newspaper for the crime of free speech, but also extending to how the UN Human Rights Commission mollycoddles these freaks -- to not give in to this dangerous bullshit. It's not okay to encase women in portable tents, and bury them to the waist and stone them for the crime of being raped. It's unacceptable to treat half your population like chattel. Nor is it cause for war, but we are under no obligation to pretend that it's merely a matter of cultural differences.
The message that needs to get through to the fundamentalists is that they are every bit as vile as the people they routinely riot against, that the perfidious machinations of the West stand toe-to-toe with their own vicious repression, their insistence on adhering to Mesolithic tribal mores twisted through Quranic misinterpretations.
And if India hopes to continue to be taken seriously as a democratic superpower, it needs to get on the right side of this one.
