France: Generals Warn of Civil War Due to the rise of political Islam

Is multiculturalism failing in Europe?
A group of retired generals has warned in an open letter that France is sliding toward a civil war due to the government's failure to control mass migration and creeping Islamism in the country.
Many immigrants, from the Arab-Muslim world, keep their religious practices which are known as "Sharia laws".
Islam has many laws that oppress women and violate human rights by authorizing sex slavery, wife beating, FGM, child marriage, forced marriage, honor killing, etc.
Islam also includes many rigid rules of modesty that apply only to women. According to Sharia law If a woman does not satisfy her husband or if she violates the laws of Islam, the husband has the right to beat her.
In most countries that practice Sharia law like Saudi Arabia and Iran under the Male guardianship policy, women are not allowed to get a job, education, or even leave the house or receive medical treatment without the approval of the male guardian (father, husband, brother or uncle).
