Unsurprisingly you are getting downvoted for pointing out the obvious. That and the continued migration from an engineering focused organization to a penny pinching bean counting org after the McDonnell Douglas reverse takeover.
Sure, nepotism and corruption also exist. Sometimes hiring managers just get it wrong, and there is nothing nefarious afoot. There are of course also "diverse" people that get unfairly overlooked because racism, but underqualified diversity hires still exist.
The context you're missing is that being "diverse" makes you more likely to be hired than you otherwise would be, but being "diverse" doesn't make you better at the job. If we had the conversation inside the guardrails you're describing we wouldn't be able to describe reality.
The issue is that the original comment is just a baseless assertion that Boeing is having issues due to identity politics, and not anything of substance. Not liking those sort of unsubstantiated politically motivated claims is not "political correctness".
