Political correctness is best mechanism for control, because you can have someone sacked for just about everything while looking justified.  Best way to fight back is to abuse it no end and file anonymous complaints against black promoters, it won't get them in trouble right away but people's psychology can easily be broken and abused. And don't think black promoters have no enemies amongst themselves, inflammatory anonymous complaints will be taken up by the enemy of the promoter (who are likely promoters themselves) and weaponized.
