Thanks.
It’s a mute point. It certainly supports James’ argument but then his argument is a dead-end argument he keeps falling back on. Well, it’s a dead-end unless you are an atheist who believes that all things in the world will continue just as they have since the beginning of human history. Christians, as a rule do not. Atheists do.
It was quite interesting. Did you make it?
It accurately shows the displacements of religion in what was then the Byzantine, or the Holy Roman Empire.
One error is that it does not show Sikhism on that map. Remember that this offshoot of Hinduism was vital in displacing Islam from north-western India.
