Yes, this thread is about people from countries that don't respect free speech murdering cartoonists in countries that do, and there's the rub. Militants in Saudi Arabia, ISIS controlled Syria, Yemen, Afghanistan, Libya, etc, access the Internet and see these cartoons, and God's law has no borders or boundaries. So clerics in those countries will call for the death of the cartoonist, as they did for cartoons in Denmark, and some radical Islamist will eventually show up with a gun to carry out the fatwa. There's an interesting mindset at work because many of them won't even question whether the cartoonist should be killed, they'll just wonder who is going to do it, or wonder why it hasn't been done yet.
And has anyone here ever said something that Christians might find offensive? Surely not. When are you going to put on a hijab or a burka so as not to offend Muslim religious sensibilities? The issue is that almost any aspect of our culture is offensive to many very vocal Islamists, who are true believers. Not executing homosexuals is offensive. Drinking is offensive. Letting women show their hair is offensive. Letting women show their ankle is offensive. This: is inconceivable. If we live our lives so as not to offend them, we will become them.
Getting back to the OP, by the most pared-down definition, journalism is writing for news media. Thus, Addison and Steele were journalists because, while they founded The Spectator and their writings could not be considered without bias, those writings were journalism. Swift's Modest Proposal, however, was an anonymous, self-published pamphlet. I submit - a gray area.
What is a Muhammad art exhibit? Anyway, looks like they got these guys with only a non-life threatening injury to one of the guards.
I was only partially questioning the spelling. Was it an exhibit of art about his life and times? Was it his image? Etc.?
