Why can’t you find an equally experienced highly qualified person of colour to do the job? Is it because they’re all uneducated oiks? That must be what you mean.
The issue comes with things like quotas, often used in DEI schemes. If the, often arbitrary, quota set doesn’t exactly match the availability of suitability qualified candidates that both match the quota requirements AND actually want to apply for the job, then something has to give. That could well be experience or qualifications.
There can limited availability of candidates that match particular race requirements as they are a minority after all.
If every major organisation has set themselves a quota like the RAF did, they are going to run out of minorities and struggle to fill the jobs.
