Actually Sunni Muslim
"Nearly all Iraqi Kurds consider themselves Sunni Muslims. In our survey, 98% of Kurds in Iraq identified themselves as Sunnis and only 2% identified as Shias. (A small minority of Iraqi Kurds, including Yazidis, are not
Muslims.) But being a Kurd does not necessarily mean alignment with a particular religious sect."
"Who are the Kurdish people?
A largely Sunni Muslim people with their own language and culture, most Kurds live in the generally contiguous areas of Turkey, Iraq, Iran, Armenia and Syria – a mountainous region of southwest Asia generally known as Kurdistan ("Land of the Kurds")."
"Are the Kurds Sunni or Shia?
And in the far north are ethnic Kurds, who are religiously Sunni, but their ethnicity divides them from Arab Sunnis. Iraq's government is dominated by the Shia majority and has underserved Sunni Arabs; the extremist group that has taken over much of the country, ISIS, is Sunni Arab."
"What is the religion of the Kurds in Iraq?
The Kurds at first resisted the Islamic invasion during the seventh century AD . They gave in after the Islamic victory near the modern-day Iraqi city of Sulaimaniya in AD 643. Most Kurds are now Sunni Muslims (a branch of Islam). About one-fifth are Shi'ite Muslims, most of whom live in Iran."
"What is the religion of Syria?
The largest religious group in Syria are the Sunni Muslims which make up around 64% of the population, of whom about 80% are native Syrian Arabs, with the remainder being Kurds, Turkomans, Circassians, and Palestinians. Sunni Islam sets the religious tone for Syria and provides the country's basic values."
Nice try but you gave weapons to Muslims.
