Actually, in light of recent developments in post-christian countries, Islam is not the one to be blamed. In some sense, Islam is just reacting to the blatant failure of the chosen people. But Islam cannot bring any solution. We have to come up with it.

Guess, what's really wrecking the world these days.
It's Christianity that didn't fulfill its responsibility. They were preparing for the Lord of the 2nd Advent, and when he came, they didn't get it. Ok, mistakes happen...
The real problem happens, when after a mistake one doesn't repent. Because humans have to move on, such people start to go off the wrong way. This is what we call arrogance. For failed Christianity this manifests as humanism, obsession with human rights, genderism, homosexualism, tolerance above all and feminism, among others. Also the obsession, to save the Muslim world.
