She should also tell you that a lot of Muslim families kill their daughters if they go out with any sort of guy, Harry. So-called 'honour' killings are far from unusual if the girl's gone behind their back, regardless if she's gone out with another Muslim. Wrong country/wrong tribe/wrong sect/wrong colour... there's absolutely nothing egalitarian about middle or higher-class Muslim families. They want their girls going to the best provider from the best possible family, within their own sect of Islam, and preferably (unless the bloke comes in with a stonking dowry for the family) from the same country of origin. They will sometimes make exceptions if the man converts to Islam, of course, and is rich enough.
The darker the colour of the person, though, the more likelihood of African slave blood, and that's one reason why the lighter-skinned girls are sought by many Muslim men. They don't want to marry into 'lowly' blood. Turkish, Egyptian, Lebanese - all prized for their lighter skins. (And those are often throwbacks to the centuries when white girls were captured from pirated ships and sold into the white slavery markets.) Black African Muslim girls? They can be the 24/7 maids and nannies. It's a complicated market place!
