And it is his religion, make no mistake about it, so he's not an objective source, especially since he's a switch hitter, a former Christian, and a lousy historian of Christianity whose popular book on Jesus doesn't pass the smell test because it stole the long ago propounded thesis of the scholar S.G.F. Brandon but never credited him or responded to it.
Here at Vox:
"Islam doesn't promote violence or peace. Islam is just a religion and like every religion in the world it depends on what you bring to it."
Islam promotes submission, means submission, requires submission. It's inherently confrontational in a way which Christianity or Judaism or any other religion has never been and he knows it. And the lying about it is not a bug, either, but a feature. Lying to the infidel is sanctioned as part of the process of dominating the infidel.
And that's the problem for the West. Islam uses the West's value of freedom of expression and freedom of religion against it, as an opening to dominate it. And like fools, we allow it.
