I don't have to fix anything, madam. Attacking me is not a good defense of islam or this most recent muslim murderer in NOLA. I don't define islam. It defines itself. A practitioner of islam is called a muslim. If you are not a practitioner then how are you a muslim? You tell me.
Not all Muslims practice Islam. Islam is a faith that teaches the importance of both belief and practice, but some Sufis believe that one is sufficient without the other.
Islam has many branches and subgroups, including Sunni and Shiite. The Sunni branch is the largest, with roughly 1.7 billion followers, while the Shiite branch has roughly 180–230 million followers. The divide between the two branches dates back to a dispute over leadership after the death of the Prophet Muhammad in 632. While the two groups share some core beliefs, there are differences in practices and beliefs, and some Sunnis do not consider Shiites to be Muslims.
The religious obligations of Muslims are summarized in the Five Pillars of Islam, which include: The profession of faith (shahādah) in God and his Prophet, Prayer (ṣalāt), Charity (zakāt), Pilgrimage (hajj), and Fasting (ṣawm).
I don't see "committing acts of terror" or "Jihad" (Holy War) anywhere in that definition, and I'm familiar with the Five Pillars.
