I already understand islam. I studied History. It is easy to understand. They worship satan and use satan’s processes - intimidation, war, crime, force, slavery, totalitarianism, brutality, immorality of all kinds to draw people away from God. What they eat or say today is unimportant - they have 1400 years of factual history showing their true nature.
Islam is completely incompatible with freedom and liberty. The death cult show be banned from the US on that basis alone.
Sunni and Shia are next door neighbors and eat the same food yet they have no qualms butchering each other.
