If you still can't see that this shit is systemic and that the religion or rather the liturgy encourages such barbarism, then you will never understand.
Truth of the matter is that this will keep happening because islam is fundamentally incompatible with modern western civilizaion based largely on Protestant culture. Those planned attacks see their genesis in mosques are in conversations after the afternoon prayers, amongst young people who share the same ethnicity and beliefs. This is further aided and abetted by clerics who say nothing, by family and friends who hear whispers but stay quiet, by facilitators who allow them to train and equip them whom they reach by contacting other friends who know them.
It's there for all to see. But herein lies the internal struggle, that of the modern renaissance man, unable to reconcile himself with the idea that some people, with different norms and values do not operate based on the same principles that they grew up with. Those same people who find in fundamental islam, which is basically the essence of the whole religion, a justification to unleash their sadistic fantasies. It's a very powerful motivator. I personally don't believe in the holy aspect of it. I think it's just some sort of rationalization which helps to intellectualize crude power relationships.
The type of modern, harmless religion that some practice and parrot out as being the true message sadly has no impact on this, because to fundamentalists, it serves no purpose and they don't think it's legitimate. The religion has never known true reform on a universal scale which is a huge problem.
Here's what's gonna happen tomorrow, after this senseless act. A bunch of community leaders are gonna come out to say that the French people will show solidarity and condemn those acts, there will be some sort of powerful mass gathering to show that they are not afraid and they will show up on tv and in the media to offer their condolences. Shit won't fly this time. Why? Because young people , children, men and women with no agenda died tonight. Innocents basically, in what is essentially the cultural capital of the world. They were slaughtered after a hard week's work, when they were the most vulnerable. It was an indiscriminate massacre with no purpose but to spread hate.
Those explanation about what leads to radicalization won't matter because nothing can allow this. No poverty, no hardship. You simply cannot condone this. It's been a trope, a platitude for far too long to explain delinquency in the 'quartiers'. Something changed today. It will never be the same again. It is a tragedy.
