Harrassment isn't 'cultural' - it isn't inherent in Egyptians.
the degree to which it is tolerated is representative of a society that doesn't protect or respect members of society.

I have been to Egypt twice... I didn't get bothered much but my blonde blue eyed boyfriend at the time got harrassed without mercy...it was relentless....

He ate an ice cream in the street and I have never seen so many excited men in my life.
