A few points here:
* the description of the passenger as being of 'African descent' is in fact a racial description, the key point being 'descent' - a white South African would typically be described as being of European descent, for example
* this is a budget airline on a flight to a bucket + spade destination where people go to eat British food and drink beer in sunshine. Not exactly a cosmpolitan clientele.
* idiot passengers on this exact same route, also on a budget flight, in 2006, caused two men to be ejected from the flight for the crime of speaking apparently-Arabic(it might not have actually BEEN Arabic), the fifth-most spoken language in the world

* police specifically investigated and the man was allowed to fly, he had also been pre-screened at the airport, authorities in this age are not renowned for being reckless about allowing dangerous passengers to fly
* my view is that the passengers would not have reacted this way if the passenger had fitted the appearance of the typical passenger on this flight - i.e. white and sun-burned.
