Re: "Diversity will destroy this company"
I have had to deal wit this problem in the past.
At $COMPANY in the deep south in the 90s, the director of operations (and a lot of the local males) considered females to be inferior; I am sure you know the type. That is not my view as I have met many women in engineering and other professions who were clearly superior to many, if not all, of their male colleagues.
There was an opening for a supervisory position in the repair department which was a bit top heavy with females (low pay and all that) so I talked to the CEO (my direct boss at the time) and he agreed I could completely anonymise any applications.
Given that I was guiding the technical operation, I was rather well placed to know the strengths (and the areas in which they struggled) of each potential candidate.
The applications were all handed to me directly and I then made new applications with the titles Candidate A, Candidate B and so forth. The operations director was livid because he could not see the names but we had done an end run around that.
Each candidate interviewed with an outside expert in management (some management skills were necessary) and that was written up with scoring.
I did the technical scoring. It had been agreed that the candidate with the best overall score (somewhat weighted as both technical and management skills were required - the solution was to multiply the scores). There were some other things such as attitudes to others and so forth - the last thing we wanted was a psychopath [1].
Now the entire process was explained to the candidates individually who all agreed it was fair and above board.
This objective method yielded a very clear winner who happened to be female. I am still amazed we managed to keep it all secret.
The operations director grumbled but there really wasn't anything he could do about it.
One of the male crew (who really wasn't that good) said he wouldn't work for a woman so he was told to not let the door hit his ass on the way out.
I am certain that had that process not been followed one of the male candidates would have been chosen.
The person chosen was the best choice from all the candidates, which is as it should be.
[1]. Certain psychopathic traits are actually a good thing. The good psychopath's guide to success is both fascinating and a pretty good read although a lot of it is in the vernacular.
