Not a flaw, an arbitrary number, could be 10% or 90%, doesn’t matter. the principle remains the same. Unless the Muslim world absolutely rejects and ends the practice of terrorism in their ranks any claims of discrimination are without merit.
Either you believe the Koran as it is written and you believe in terrorism as a means of creating a worldwide caliphate.
OR
You do not believe in the Koran as it is written (moderate Islam?), and you are an apostate. You are then subject to terror and death.
