85% are Sunni. There have been people converting to Shia.
Amethyst flags oldfart's post as offensive. I think/hope? its getting upset by "Shi'a" without the "'". This post is testing that theory Adding Palestine #palestine for consistency
shi'a is the lesser common variant of islam, it's more authoritarian
Shi'a / Sunni split in Islam parallels the Latin Rite / Eastern Orthodox split in Christianity pretty well. Each is internally fractured as well, so its hard to make any generalisations outside the actual theology.
For what i know shia is people who think the sucessor of Mohammed should be someone from his blood. Sunna is who says the sucessor should come from community trust. It is not, per Definition, authoriatarian, but might be or not a characteristic of it's currently followers. I'd say that electing someone by blood sounds less democratic then by Trust, so you might be right
