Muslim, no sect
They are Muslims. It is irrelevant to think about which sect they belong to. No sects in Islam with same meaning as in Christianity. The sects in Islam are more or less different schools or different groups that differ only on minor historical issues.
Islam is not a sect. It is a religion, which contains sects.Members of the Islamic religion are called Muslim. The major Muslim sects are Khawarij, Shi'a and Sunni. Each of those sects have sects.
The Quakers
In the days of Saddam Hussein, Saddam, himself a member of the political ba'ath sect of Sunni Islam, viciously suppressed any kind of individualism in his Iraq. He attacked Shias in the south and east and Kurds in the north and any Sunnis that disagreed with his ways, and held his country together with an iron fist. Following the fall of Saddam, the Shia struck back against the minority Sunni for Saddam's oppression, who struck back at the Shia, who struck back at the Sunni, and the whole time the Kurdish north is wanting their independence from a mostly Arab south (less so in Iraq, however, as the primary Kurdish beef is with Turkey, where most Kurds live and where independence is most deeply sought).
