The Oxford dictionary gives the following origin of the verb "recognize": from the Latin recognoscere: "know again, recall to mind". It's probably unpleasant and certainly disconcerting but it's a gain of time to realize from the very beginning this simple fact: in order to recognize something, we need to already know it.
We are certainly not obliged to get to know something if we do not wish to. One has the right to feel physically appalled by a drawing and refrain from learning more about the cultural background that gave birth to it. In the very same way, he may refuse to even taste Camembert cheese because the very smell discomforts him or, to be frank, disgusts him. Any reasonable person should respect this fundamental right of "refusing contact". But as sincere as this may be, it is a personal reaction. You have the right to feel disgusted when "your stomach" refuses to digest Camembert but please, don't generalize. Your stomach is not the center of the world, plenty of descent people like Camembert and are not to be categorized under your stomach's reaction.
Did I find the Charlie-Hebdo/Aylan drawing funny? Certainly not!
Bitter irony is rarely funny. But that's precisely the idea. And it's ironic that people who fight racism by imagining and quoting with bitterness the very disgusting and potentially unlimited obsession of racists, are perceived as racists themselves.
Pierre Desproges, a Parisian whose bitterness forged my generation's ethics and relation to humor, made shocking jokes about cancer. Although he claimed on stage "I don't have cancer, I'll never have cancer, I'm against it", he actually had one and passed away from it. Desproges thought about humor, irony and their limits in a very serious manner. We can laugh about everything, he said, but not in everyone's company.
Please keep that in mind before tweeting your unquestionable rage.
Aylan's family, who have every right indeed to feel outraged by anything approaching their son's memory, without wasting time with semantics, have been decent and temperate in their disapproval.
