You can't generalize here and say that all Muslims are the same and have the same thinking.
For example, Muslims in Balkan, Turkey, Kosovo, Macedonia, Bosnia, Albania, Croatia are very different than Muslims in Saudi Arabia.
Muslims in Balkan live peacefully and without any problem with their Christian neighbors for centuries.
So, it's the fact that Muslims and Christian can live together without any problem.
Unfortunately, Muslims in Saudi Arabia, Pakistan, Afghanistan etc. are brainwashed by their radical religious leaders and believe that they are superior religion and that they should fight Christianity and they see Christian people as enemy.
So, Islam is not problem here but interpretation of Islam by some Islam radicals.
I'm not buying that point of view. That's rather like saying for the population of some island inhabited by cannibals, 51% must engage in the practice before you can call the Island an island of cannibals.
