Citizens in Burundi, Rwanda, Uganda and Nigeria were not equal in practice although the law stating that everyon was equal.
In South Africa, people were not equal in practice and the law backed them up.
In the first group of countries, you had criminals running the government. In South Africa, to treat people equally would have been criminal according to their laws.
And if you can't see that there is a difference, you don't know what you're talking about.
You are delusional.
