I guess OP is referring to stuff like Trump's baseless claims that DEI was a factor in the recent plane crash. I hope we can agree that that's an absurd position regardless of our own perspective on DEI.
A single person's allegation of being passed over is a long way from proving that DEI policies contributed to staffing shortages. Moreover the audio from the recordings shows that the helicopter was warned and advised to avoid the plane, suggesting that staff shortages were not a crucial factor.
If you want to discuss the helicopter in particular, there’s also questions why a pilot who had been in multiple desk jobs for multiple years was flying a high risk route like that — and the possible reasons the military promoted her and allowed her to attempt this with questionable competency.
