An Egyptian secular newspaper tries to figure out why some people are afraid of the number 13.
It can't figure it out (apparently Egyptian reporters are even lazier than their American counterparts who at least rely on Wikipedia) , but it says anyway "It is certain that the Jews are behind the smear of the number 13 and they tied it to bad luck, especially when the 13th of a month is on a Friday.... The Jews believe that there are 12 tribes and their awaited 'Antichrist' will come out of the tribe No. 13 and they will consider that his appearance represents a victory that the Jews who are seeking to achieve and this is the reason for their obsession with the number 13, which symbolizes their power and cosmic dominance, and this is why the Jews were promote the number 13 to be unlucky to Muslims."
It would be wonderful if some social scientists would analyze why so many Arabs - the intelligent ones, who write for major newspapers - are so freaking crazy. But it would be career suicide to do something useful like that.
