Re: 12 - it’s more than that. The number of ignorant comments on the Internet claiming that such problems are due to DEI is notable. No direct knowledge of the circumstances, maintenance actions, etc.
In one case, someone posted a picture of a black NTSB team member and the DEI hire comments started. In that case ignorance and racism combined.
Pretty illuminating.
The problems that DEI has caused are also notable. Those of us who were in the work force in almost any vocation for several decades saw many examples. The problem has been worse in large corporations and the government. Dismissing those who often correctly attribute failures to affirmative action and DEI as racists is not going to fly with those who have seen issues first hand.
