I want to be convinced, but your posts don't help.

Three posts up, your only citation was to Wikipedia, claiming 20% of whites were against apartheid. But the paragraph in Wikipedia itself doesn't cite anything. I hope I don't need to say: Wikipedia is not in and of itself a source. Either they need to cite some sort of an underlying source, or you do.

The post I'm immediately replying to has one citation to a source about Black ownership of land. That's not what's under dispute here.

Can you provide some actual sources substantiating the claim of what percentage of whites actually did (or did not) support apartheid? Otherwise your posts are pure rhetoric.
