No, it is the same as the rest of Islam. This is a religion that has exhibited killing and war over peace, while using God as their hammer.
Before Mohammad died he went into killing to protect his religion, and this has been an indirect attribute since then. As a prophet, he failed to appoint his successor, and this led to the different factions of Islam killing each other as they fight to follow a worthy successor to Mohammad. This would not have been an issue if only Mohammad did it before he died.
Islam has NOT changed since the Crusades, other than they have taken their war around the world. Surely, Allah could settle the issue, but he has not, so the blood baths continue.
Is it fair to say these things about Islam, yes because they are true. Does it mean that all of Islam are killers, no? But until we can tell the good from the bad, the deaths caused by the bad speak with more volume than the good.
ISIS is just a continuation of Muslim Terrorists. They haven't changed, so I haven't changed my view on them.
