Just scanning through the old articles. I can't see where it was debunked, but I can't see where it was proved either.
Having gone through a great many pages on Google, the ONLY references to this at all are this article, or a variety of moron rant pages or blogs referencing the article.
I think it's safe to conclude it's nonsense. It's amazing how quickly people completely ignore sources when they see something they want to be true.
I just met a young woman who has recently arrived here with her family from Russia. During the interview she adamantly insisted that she was a Turkish Muslim but was born in Russia.
They keep a coming...Somali Muslims, Iraqi Muslims, all kinds of Muslims...where will it end?
