at the end of the day all muslims will follow their book or be counted as apostate,
They will follow, but they will interpret it differently, just like Christians will have different interpretations of the Bible. Some Bible interpretations have led to violence historically, the KKK being one example. There are even some instances of Christian-inspired violence today, but by and large we have grown out of it.
Muslim scriptures present a greater challenge, I admit. The passages that exhort violence are explicit. But research I have read indicates that Muslims who agree with violent jihad against Christians and Jews are a minority overall, and minorities in most countries, with some notable exceptions like Iran and Pakistan.
But painting all Muslims with the broad brush of “people we should hate” is un-Christian and as unfair as saying Timothy McVeigh represents all Christians or all Catholics. FWIW, he was raised Catholic and said to the end he followed Catholic “core beliefs.”
which islam does al-qaeda follow?
Al-Qaeda comes from the Sunni tradition, but the version of Islam they follow is their own.
