If you say so
You're talking to someone who flew as FO with a top rate black captain over thirty years ago and subsequently had a black head of training in a sister company.
Don't try to stifle comment by playing the race card; that's so passé.
I'm not sure what your point is? You worked with black people so you know everything abour their experience of racism? Or that because you knew a couple of successful black people, racial discrimination doesn't exist?
