When Muslims get over a certain % things go downhill quickly. Below a certain % they are the best mannered. Then people think well of them. Then the % grows and jihad starts with the youth and the parents saying "we can't control our children. They are doing these violent acts on their own." Then the % grows and you have a Muslim country. This is a common thread of how they took over many countries. See the history of Spain and the Martyrs of Cordoba.
