Just a bit!
I'm not enough of an Islamic scholar to call that on my own authority, so what I (and you) have to do is to hear and weigh, as best we can, the counter-arguments from non-ISIS Islamic scholars (i.e. representing 90% or more of the Islamic world)
That means giving them a fair hearing, and not automatically thinking that they are painting a softer picture just to lull the west's suspicions.
(Though, as with any religion, there are those who cannot see or admit the slightest flaw or problem in the history or current practice of their own faith. )
Do remember that both Al-Qaeda and the Taliban have condemned ISIS for being too extreme.
That has to take some doing.
And consider reports coming out from inside ISIS controlled areas as to just how the "Islamic Caliphate" is working out in practice... It doesn't seem to match the propaganda.
And one little positive bit of news, from elsewhere.

"A group of Kenyan Muslims travelling on a bus ambushed by Islamist gunmen protected Christian passengers by refusing to be split into groups, according to eyewitnesses."
The unity, the solidarity there was not Muslims together. It was normal, non-violent people together.
At the very present risk of getting shot for doing so, as far as the Muslims were concerned.
I can only hope I'd stand between a mob and a Muslim, or a mosque, should the need arise.
Not a bad way to go.
