Nazis aren't interested in debate, they are interested in dogwhistling the most awful bigotry.
The most politically successful far right candidates of recent years aren't particularly skilful rhetorically or intellectually.
That's because Nazis don't see debates as debates, they see them as an advertising opportunities. All they have to do is say to potential voters: "we're on your side, we hate the foreigners too", and the debate becomes an irrelevant sideshow.
