What is Racist is that Boeing is using perceptions about foreign airlines to shift blame and scapegoat... when clearly Boeing was the party trading safety for profit here. Boeing, "the Americans", knew and did nothing. There is no evidence that more flight time or experience would have changed the outcome. Who has 5,000 hrs of MCAS fuck up protocol? Sometimes those with less experience handle new technology better.
I doubt it was racism when regular American (and Western) chauvinism is plenty to do the job of discrediting a third-world airline--not to mention that most Americans couldn't tell you what race Indonesians are.
