As far as I know, emirates do not ask for a photograph when you apply and neither do you have to specify whether you're black, white or blue. So Banjul, my dear, Emirates DON"T KNOW WHAT COLOUR YOU ARE and your post is totally irrelevant.
As has been mentioned, we have a number of black pilots flying for us - I personally know at least 4, and they're all great guys.
EK, with all its (many) faults, is anything but racist when it comes to pilot selection. The mix of 60+ nationalities, religions and races are testament to that. If you're trying to make an issue with your skin colour, then you have no place in EK anyway.
