It is the inhumane act that should be our entire focus. Anything else dampens the universal condemnation that should follow something as devastating and as unacceptable as this.
I've deleted the majority of this first quote, because I agree with everything up until the above.
I do think we need to address the source of all of this. But when we dig far enough down, it's not the offensive cartoons that we will find there. IMO, it is Islam, and the way the Quran and even Sunnah are taken as the literal word of God, and the way Mohammed is taken as a perfect example for all mankind for all time. It is that that we need to work on, not offensive drawings.
We've barely started digging, let's dig some more.
I was not claiming that we would find "Charlie Hebdo" right in the throes of Islamic scripture. I also was not saying that the offensive cartoons were the source of everything. I'm saying that whatever worldview the murderers subscribed to, it was manifested in the slaughtering of the cartoonists. People drew cartoons of Muhammad, some overly murderous crybabies then took it upon themselves to kill the cartoonists. Just because the seriousness of the murder far outweighs the seriousness of the depictions, I don't see this as a reason to ignore the cartoons. As aforementioned, this would mean that we are neglecting the stimulus (or perhaps, one of the very many stimuli).
tl;dr: We will draw cartoons of Muhammad. You have the right to criticise our actions at any given moment, but nut jobs don't have the right to murder us.
I'm subscribing to the idea of "natura non facit saltum", with regards to reformation coming in a manner that is akin to chipping away at a block, rather than bulldozing a house of beliefs down.
However, I'm not saying that we shouldn't attack Islam as the source of this. What I'm saying is that I've yet to be presented with an argument that convinces me of the following: " We should focus on the inhumane act only".
I say we treat the issue holistically, and realise that most people understand that "murder is wrong" is self evident. But for some reason, some of those people don't realise that "murdering cartoonists who draw images of Muhammad is wrong" is equally self evident.
We need to work on both the disproportionate reactions behind the cartoons (which involves giving weight to the actual cartoons) & the Islam behind all of it.
