They are typical style for Charlie Hebdo cartoons. Everyone is portrayed as very ugly.
Like I said, these particular ones weren't the ones making me clutch my pearls, but I do understand why some people would consider many comics poking fun at Muslims racist, depending. But not because of the criticism of Islam, but because many of them represent Muslims as ridiculous exaggerations of people with features we in the West typically associate with looking "Middle Eastern" and then depicting them as barbarians and dirty and primitive and what have you. If
someone wanted to level that accusation at these cartoons, I'd at least be able to see where they are coming from, but if it's because, like countjulian suggested, they criticize Islam, I won't even entertain an accusation so absurd. It's simply not racism in any sense to criticize an idea.
Anyway, yes, like David mentioned, it's not the issue right now. That this was brought up in the immediate aftermath at all points to attempts to confuse and distract from the issue and shift the blame to some degree onto the cartoonists. I reckon I shouldn't have tried to answer it, considering.
