Well, the Muslims claim that the Roman Empire was no match to their false faith, when Constantinople fell into Muslim hands, either. In fact, they use this very incident as a fulfilment of Muhammad’s prophecy that this centre of Roman power would collapse onto their hands.
The truth is, empires always fall, powers always shift.
I know by your posting history in this incarnation and your previous account, that you are no friend of of religion in general and Christianity in particular.
You will likely never acknowledge any good that can come from it. That’s your choice, but it will not change the facts.
Atheism will never be able to stop islam and Christianity is the only religion which offers the only alternative which has the power to do so.
And those who know a little bit about history know that this is a false claim, so why would you promote it? Does your intellectual relativism have any limits or does any argument suit you so long as it makes you look intelligent?
