You are falling for their BS.
The evidence of the real stand of things are muslims, that are fighting against salafists.
In this way You have nothing to say, that muslims are supporting ISIS.
The BS is Your font of text extraction equilibrists for ignorant people in questions of modern Islamic World.
You have specified text about all the questions in criminal activity of ISIS from muslim point of view with the reference to text of Quran and the Modern Rules and the Stand of things in Islam.
The letter explain that being "non muslim" rappresent no crime, even being in appartenance to other religions rappresent no crime too.
(The exceptions from this are cases of witchcraft, Satanism, Sexual disorders. I have few data how they deal an all that cases.)
Try to ask to some expert where is the trick of insane diffamation in Your font, if to You is not enough so clear text of letter.
No idea, who have the time to make it for free and online.
The good Muslims are bad people
..The bad muslims are good people
..OH Yes it is?..Islam started in Mediterranean region, in the Hejaz area of modern Saudi Arabia..
So what type of muslims are Saudi?..
Then don't you think they be the first to know how is the right way to preach ISLAM?..
And is ISIS not like saudi arabia good Muslims?..
You see it spread from that region and people started making bits up as time went on?..
And this is why we have so many different type of muslims..
People making things up as they go along
..And maybe that's why loads of trouble 
..Instead of keeping it REAL
..We can all say blah blah blah blah..
BUT it's all about the money?..Yes even your flying?..
To scared to die because you cannot carry on spending..No spending no existence
..IT'S ALL ABOUT THE MONEY..EVERYTHING
..Money is the biggest killer ..
