In my experience, Muslims aren't in the least bit 'offended' by Christianity.
I've argued with them about it, in places as different as Peshawar, on the North-West Frontier, and Whitechapel, in the East End of London. And I had the impression they were relieved to find someone from the West who didn't fawn all over them.

As in C.S. Lewis' famous observation from The Abolition of Man, we laugh at honor and then are shocked to find traitors in our midst. We castrate and bid the geldings to be fruitful. Examples of this myopia can be found everywhere, in every field of human endeavor -- at least in every field of human endeavor that the wooly thinkers have gotten to. For example, envious whiners on the left want everyone in the world to have access to middle class wealth, no poverty anywhere, yay, but they have nothing but contempt for those middle class values that would make such a desirable thing possible.
Liberal Anglicanism has become a laughingstock to both ends of the belief spectrum, and rightly so, I'm afraid. One can only hope that it will wither away into the irrelevance it so richly deserves, and seems to desire.
