There is a very good reason for Muslim women wearing the Hijab (from googLe):
'The answer to the question is very simple - Muslim women observe HIJAB (covering the head and the body) because Allah has told them to do so.'
Reminds very much of a TV commercial some years ago, which promoted their news bulletin with the slogan 'Brian (Henderson I think) told you so' on the premise that if Brian told you it MUST be true.
Great RATIONAL thinking isnt it? You do it becasue someone told you to do it.
