My advise as someone who has experienced this in many parts of the world including my own Country. Most people are subtle about it and I beilve it is their mental shortcut to gaining the upper hand in a negotiation. They are not doing it because they think they are truly superiors. So instead thinking world is unfair (racists, sexist etc.), I try to respond appropriately and in the moment.

Current crisis is a direct result of people attributing too much meaning to simple negotiation tactics.
