What a load of fucking nonsense.
No, the people who worked at Charlie Hebdo didn't deserve to die, and no, the killers didn't have a point.
This was true when the killings took place, and it's true now, and it will continue to be true however many cartoons they continue to publish.
It would be true even if the cartoons were racist (which none of them have been, for reasons which have been discussed at length here, even if some people are unable to understand or accept arguments which require them to step slightly outside of their own individual world view).
And it's true even though some of the cartoons are offensive, which they are, but not as offensive as the events which inspire them and which they are satirising, in this case a food manufacturer using this earthquake tragedy as a fucking marketing tool for one of their pizzas.
You silly, silly cunts...
