A really good example of why you shouldn't read The Guardian. The article reports Moz as saying the 'Norwegian killings are nothing...' whereas what he actually says is 'We all live in a murderous world, as the events in Norway have shown, with 97 [sic] dead. Though that is nothing compared to what happens in McDonald's and Kentucky Fried shit every day'.
Although he gets the number of dead wrong, it's clearly the numbers he is referring to. '97 is nothing compared to the millions...'
He expresses no disrespect to those killed and I don'y think intends any. He merely alludes to the fact that millions of animals are killed every day in factory farming. You may disagree with him with regard to the morality of that comparison - and whether just comparing numbers is respectful to the human beings slaughtered in Utoye - but just in terms of numbers the comment is factually accurate. It is a shocking comparison, no doubt. But using shock to jolt people out of complacent ways of thinking is not unusual.
Plus the comment was made at a concert, to a paying audience who came to hear Moz sing and make a few controversial comments in between songs. That's part of the deal. At a concert that probably showed footage of animal slaughter to that same audience whilst singing a song called 'Meat is Murder'. It's all part of Moz's animal rights stance that he has never shied away from. To quote a comment out of context, as the article does, in the name of the 'take offence at everything brigade' is always a zero sum game. As recently demonstrated by the fuss over specific jokes made by Jimmy Carr, Dave Chappelle, and currently Ricky Gervais, reported out of context from hour long shows, attended by a paying audience, and broadcast on a subscription TV channel.
