The Islam problem is not something that is tied to "Western elite". Stop tying this issue to your dogmatic world view.
This is a terrible event and I hope Europeans take better measures against these things, including a new approach to the question of Islam (such as not defending it) so as to not give way to far-right movements feeding of these events.
Although most Muslims are not such extremists, Islam has a tendency to produce an anti-democratic mindset. This is an issue related to many variables including the cultural forms of Islam that evolved up to this day, the domineering political movements and cultural images-behaviours people embraces (especially in the West) and an attempt to become a "counter-culture" of mostly youth within Europe is something that is headed towards dangerous places.
Forming of large Muslim communities within the West prevents proper integrations and entrenches the more fundamentalists views. By this point, many young Muslims in the West seem to feel alienated and radicalism seems to have strong roots by now.
I am an atheist in a Muslim majority country. Since I do not believe in Islam, there is no point in debating "true Islam"...but what matters is the domineering cultural forms that are emerging from within Muslim communities. And while majority is perhaps becoming part of the global world, a really significant portion is adopting these counter-culture forms that are still very strong.
Unfortunately, Islam has not gone through what Christianity did, an indepth internal conflict over the role of state and religion, democracy, diversity of beliefs. Even in Turkey, the countering of Islamist reactionary movements were done by replacing Islamism with an alternative nationalist-cult following, kept by the iron-hand of an army which is failing today. Similar situations exists in Egypt, Syria and Iraq. Even the relatively more "sufism" oriented Islams of far East are starting to produce more radical versions from among themselves.
As Macron have said, Islam is going through a global crisis and it is not going for the better.
