We should be doing that here.
I think it's difficult, not because we've imported so many, but because a sizeable percentage of the native black population seems to think Islam is cool. They think that Islam sticks it to Whitey, forgetting that the slave trade was largely run by Arabs for hundreds of years. The size of the problem can be judged by the high percentage of Arabic names given black children. Not to many Mohammeds, but a lot of Kareems, so to speak. Go figure.
