According to a new (and scary, I might add) book called “Islam: What the West Needs to Know”, Islam is a political movement and not a religion at all. The author was interviewed by Tucker C. and said that Islam has always been about world domination. That was the goal from its inception.
(Not sure if I have the exact title correct.)
I hope the author doesn't think this is news.
In Islam this is a distinction with no meaning. So Islam is not one or the other, it is by definition both.
