Demonising them by denigrating their religion and equating their behaviour with that of a handful of extremists and criminals,

I do not do that, but the "handful of extremists" (the security services are aware of thousands!) are a serious threat and it is foolish to think the "spooks" are lying to you about it.

As I have said over and over again, the Muslim communities are among the most law-abiding and industrious of all British citizens.

You have said it over and over again but never once supported it with any facts.
They are in fact significantly over-represented in the prison population and the gap is widening.
