You don't think that glorification of motherhood and building a transportation system are good in and of itself? Of course they're not saying that Nazism in general was a good thing, but there are certain aspects, that taken by themselves and not taking into account the context of the situation, are good. With everything good, there is always a little bad, and with everything that's bad, there's always a little bit of good, that's how the world is.
Just because there might have been 1% good, it doesn't change the fact that it was 99% bad. The question they were posed is whether there are SOME good aspects of Nazism, not whether it was good as a whole.
