Racial categories are relevant to a historical understanding of the apartheid regime for the obvious reason that the regime itself divided society along racial lines. For example, only white people could vote in the referendum you’ve referred to. If you are bothered by statements such as “many white South Africans supported apartheid” (even though you appear to acknowledge that they’re true?), then you should blame the apartheid regime for the relevance of this racial category, not me.

It is obvious that not all white South Africans thought alike and that many opposed apartheid to varying degrees. It is also obvious that the vote to repeal apartheid was an enormous step forward. As I’m sure you’re aware, nothing I’ve written contradicts this.

That the regime divided people on racial lines was what we were upset with, because they weren't applicable or useful.

I think trying to bring it back to "white people" when they overwhelmingly voted not to do that is disingenuous.
