Excellent essay, read the whole thing.
But I will say this...
As much as I like Mr. Steyn, and Daniel Greenfield, and Robert Spencer, et. al, they talk and talk and talk and talk and talk and talk and talk and (had enough?) talk about the problem, but never offer a proposition on what to do about it.
I've seen much of the same from posters here in this forum.
I'm one of the few who has postulated the solution.
My proposition is radical, and I would fully expect to be condemned for stating it, but oddly enough, no one ever seems to comment one way or another. Perhaps I'm on more ignore lists than I realize. ;)
Perhaps the realization is that a true solution is simply too difficult to imagine or accept, and the only palatable response is to turn away.
I suppose I can't blame people for doing this.
But to do so is to acknowledge, and perhaps accept, the death of The West.
Like Steyn comments towards the conclusion of his essay, we have become the Elois, and the muslims are the Morlochs.
From where will come George, the time traveler, to save us?
