Culture not color!
As much as I dislike the insinuation that people of one race are inferior to another, I also have a big problem, ATSU, with people like you who try to make any comment about aviation CULTURE turn into a discussion on racism. It has been tried before on this forum and I believe the conclusion from those threads was that we enjoy a very diverse and professional culture on EK flight decks.
However, and I am sure that you will agree, the fact remains that some regions have a less than healthy aviation culture and certainly not as mature as those that are currently inhabited by populations of a predominantly pale complexion.
There is enough hatred, violence and racism going around and I would suggest that you find your son an activity other than one that will only foster further hatred and fear between people of diffent colors.
