No, this doesn't refer just to Islam, it refers to all of us.
The cowards who want us to draw the sword against innocent and defenseless Moslems are referred to here.
Of course, you are correct. While the hatred in Islam is evil, it is also contagious.
And Satan just smiles as we respond with the same kind of anger and hatred Islam pours out against us...its like starting a fire that just keeps spreading.
I spent much of last night tossing and turning over this very issue. How do we kill Islam without catching its disease ourselves? Surely, there is a way.
And he said unto them, When I sent you without purse, and scrip, and shoes, lacked ye any thing? And they said, Nothing. Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
