So new-born children of Muslim parents are counted as Muslim as well? If that is the case, then it is no wonder that it is the "fastest growing religion", with 8 times more children being born per family.
Christianity doesn't work that way, you are not a Christian because you are born from Christian parents. If we started counting like that, we'd probably have some more…not that numbers really say anything.
That said, how is an economic system going to support a world that has 8 children per family? Sounds problematic to me.
To the point: if this video is true, then I'll probably be alive to see this happen. A strange idea it is, to think in some hundred years there may be no more Dutch people at all :P
You have to hand it to them (Muslims), they sure are very effective in what it is they're trying to do. And if the video is right about its claim, then there is no way to reverse the effects (not even by having 8 kids per family ourselves? :P)
