JIM ASKS:
Muslims in the U.S.: Sunni or Shi’a? And a second reader asks about the two groups’ numbers and over-all relationship on the international level.
THE RELIGION GUY ANSWERS:
This two-sided split underlies the increasingly dangerous Mideast rivalry between a rising Shi’a axis under revolutionary Iran and a bloc led by Saudi Arabia with its strict Sunni regime. A 2012 Pew Research survey asked people in Sunni lands “do you personally consider Shi’as to be Muslims or not?” Those answering “no” ranged from 37 to 52 percent in Egypt, Indonesia, Jordan, Morocco, Pakistan and Tunisia. This troublesome rejection of Shi’a religious legitimacy is enforced with a vengeance by the bloodthirsty “Islamic State” that purports to have restored the Sunni “caliphate” within Iraq and Syria.
On Jim’s question, there’s considerable dispute about the total of U.S. Muslims but Pew estimates 10 to 15 percent are Shi’a, roughly the same as in Canada and Britain. Iran contains some 40 percent of the world’s Shi’as, followed by sizable populations in southern Iraq, India, and Pakistan, and smaller numbers across Afghanistan, Azerbaijan, Kuwait, Lebanon, Nigeria, Oman, Qatar, Saudi Arabia, South Africa, Syria, Turkey, United Arab Emirates and Yemen.
Globally, the Muslim population estimated at 1.5 billion is heavily Sunni, with a Shi’a minority of perhaps 13 percent. Some say followers of Sufi mysticism form a third branch of Islam, which is more or less true, but they overlap the other two categories and are hard to count. (This over-simplified discussion will omit many Muslim variants and those regarded as heterodox.)
The Sunni vs. Shi’a schism was as much political as religious.
