Hey, when you have villains as useful as Evil Eighties Afrikaners, you use them.
Reading the review, I was reminded a lot of another sci-fi alternate history story: Guns Of The South. Don't know how close the two are, although the latter "solved" the problem of neither side being sympathetic by whitewashing (no pun intended) the Confederates and making the time travelers cartoonish puppy-kickers.
