The best way to deal with people, whom you believe have extreme views, on bulletin boards is to ignore them.
All you are doing is pouring petrol on a fire that was not burning very well.
Or to put it another way, do not dignify their rantings.
I am taking two British Arways flights later today and will not give this poster a passing thought.
My only concern is whether the service in Club Europe will be any good, as it has been poor on the last two.
