Only tangentially related but South Africa and races reminds of an intense (I use the word lightly) ongoing debate in r/cricket.

South Africa has a very tiny white population but most of the major cricketers are white. So in light of that, the South African government decided that a racial quota system will be instated, making the presence of at least 6 non-white players mandatory and at least 2 of them must be African black.

This has resulted in repeated unpleasant discussions over whether certain players are in the team merely because of their color.

The fact that many up-and-coming white players (examples - Kyle Abbott, Rilee Rossouw), have decided to jump ship and quit international cricket in favor of more stable and secure county cricket contracts in England (using a deal called Kolpak deal) hasn't helped matters.
Making your way into a team of the best 11 players in the country was tough as is. Doing the same with only 5 spots available is a pipe dream for most. You're essentially competing with THE best 5 players in the country.
Brexit has also hastened this exodus as after UK leaves the EU, Kolpak will not be possible.

The failure of the South African cricket board to implement this change satisfactorily caused it to be banned from hosting global tournaments by the government.

I guess the point of my digression is that South Africa still has glaring flaws in the way it deals with racial issues.
