Sounds like you have a local problem with organized crime, and that some of the local crime bosses happen to be Muslim just as the crime families that rule much of the U.S.’s urban areas happen to be Catholic.
Leftists have always allied with radical Muslims ... from when Muslims brokered tribal peace in Arabia, to the popular revolt of the Shi’ites and the Kharijites, to rooting out caste privilege in India, to when the Almoravids and Almohads rebelled against a conservative Muslim establishment in the name of equality, to the rebellions of the Tukulor Empire, Mahdi Army, and Houses of Hashim and Saud against European imperialism, to the Algerian, Palestinian, Sahrawi, and Kurdish fights for self-determination and revolutionary social reform, to the struggle of Muslim fighters in Malcolm X’s groups, theBlack Panthers, Pan-Africanist Congress, and Black Liberation Army, to the Muslims in the fight against ISIS.
But there are radical Muslims and then there are radical Muslims (just as there are leftists and then there are leftists). The most infamous radical Muslims tend to come from the right (Ahmed Yasmin, Amin al-Husseini, Khomeini, Osama bin Laden, Abu Bakr al-Baghdadi, Omar al-Bashir) or center (Moammar al-Gadhafi, Idi Amin). And the left seldom allies with them ... although it defends any colonial or semi-colonial leader in a conflict with any imperialist power, without preconditions.
