God doesn't know what path humankind will take, and it's because human beings have free will
If God doesn't know that, then surely Michel Houllebecq knows. Didn't I add Monsieur Houllebecq into my sentence, you smart ass?
only God (or Michel Houllebecq) knows what path it will take
Look at the North of Ireland where white people, both of Christian denominations with many shared cultural norms couldn't co-exist peacefully
NIreland is a very good example against what Polly says about white Christians vs. brown Muslims. But is it really against it? Only in part, namely in that part concerning the white against the brown, and it seems to me that religion is a much more important factor, in fact is decisive factor as the cause of a struggle between two communities living together in one state or one province fairly isolated from the mainland as is NI. Language is not a problem, the skin colour is not a problem, but religion seems to be one. In a broader sense it is the system of beliefs of which religion is only a part, but a decisive part, the "organizing" part, if I may say so. Notice that the conflict of a similar nature as in NI slao happened in the the slowly crumbling Yougoslavia of the 1990s. All whites and all Christian, those living in Serbia and Croatia plus the Muslims people in Bosna and you have a barrel of gunpowder, as we say in Polish, ready to explode when favorable circumstances for that arrive. In Poland you could see the (peaceful) zeal with which the Polish state pressed the Orthodox church for uniting themselves with the Roman hierarchy, the action which was largely successful, but next you could see the enormous zeal, often violent, with which the Russian empire pursued to reverse this process after the dissapearence of Poland from the map, an action which was also largely successful. And let's not forget the St. Bartholomew's Day massacre in France among many other conflicts of this type. So religion which embodies and organizes a system of norms and beliefs and next transforming them into the feelings of (national) identity is what matters most.
A natural question that arises out of this is: are we able to eradicate religion in the hope of putting an end to numerous such conflicts that were taking place so far? As an answer, I recall several reports describing radical Muslim ideology in Europe. These reports quote those Muslims as saying they absolutely despise white Europeans who are atheist as being complete null in their eyes in contrast to white
Christian Europeans whom they treat as enemies, but enemies equal to themselves. And that's the big difference in norms and beliefs between those two worlds of which those Europeans willing to welcome herds of Muslim people arriving in Europe do not seem to be fully aware of. Nature does not tolerate vaccum and if a religion falls down, next there comes another one willing and ready to take over the empty place.
And I am saying all this as an agnostic rather than a religious man.
