I think we need to be objective here.
Islam is hijacked by terrorists.
Just like christianity is hijacked by crusaders of old, and modern neo-crusaders.
Buddhism is also hijacked by terrorist monks killing Rohingya babies.
I think you are very much missing the point, Servant.
Islam is often accused (fairly, IMO) of encouraging such hijacking (as is Christianity to a somewhat lesser extent).
There are good reasons for that. Islam is centralized, judgemental, theocentric. Once one convinces himself that he or she is doing God's work by causing harm to someone else, there is really little that can be done to show him or her better.
Even when it is acknowledged that a group of Muslims went stray, the attempts to correct the practice end up all too often being arguments of authority, even outright appeals of hope for the coming of a Caliph or some other figure of authority.
I just don't see how a doctrine that claims to be guided by God himself and that encourages so little self-responsibility can
not end up hijacked (sincerely at that) by people taken by hatred.
