Hypocrisy, I am neither egyptian nor muslim, but I can tell you that much of what you have described applied to the experiences I had of Egypt. without the kidnapping... but I did have literally scores of men calling my number after one managed to guess-dial it, and I answered it thinking it to be a member of my family...
Course, my 'H' had the same, but with many (22 in one month) women throwing themselves at him cos word had got out that I had gone home and his needs weren't being met 
I had friends that were pretty near assaulted, by huge groups of men.
BUT I say again, IF this were a MUSLIM issue, then the Christians in egypt would have their women living to a different level, they would have equality within their relationships, the girls would not be treated like dirt.
This is not the case, it matters not what religion you are in these cultures where women are mistreated. You will be shat apon regardless.
Religion IS however he big white stick, the BECAUSE to any random WHY... but this is cultural control not religious control.
Western Mediterranean and indeed Greek cultures are mis-matched when it comes to sexual equality too, albeit to a lesser extent than their North African Eastern Mediterranean neighbours.
Men from Italy, Spain, Portugal, Greece are all expected to be out and about having fun, sowing wild oats etc while young girls are not permitted the exact same freedoms. They are mostly, and officially OFF limits.
What religion you are here makes no difference it is merely the back up big stick to beat miscreants with.
