The recent incident should not be linked to racial discrimination in any form. Just try to answer this question yourself: will the airline crew risk their jobs just to discriminate an individual or a group. The officer/crew will be fired if the airline finds no reason of suspicion. So, racial discrimination should be thought as the last reason of detention. Hence, the crew did the right thing in suspecting and imagigining the worst that the act of those irresponsible idiots could lead to. If you don't want to be identified as the "bad people" or "potential terrorists", then do some good acts yourself. And important thing is that "you people" who think they are being discriminated, should come forward and condemn openly, or at least actively, such irresponsible acts of "your people" and not shout at those who are trying to work hard to secure lives of innocent people which are in danger because of some extremists belonging to certain region or religion. I wouldn't mind extra security check to assure that I am no danger to anybody. So, cooperate, don't rebel.
