Yes indeed, because I think people have tendency to view those methods as the ideology itself while pretty much any dictatorship with any ideology employs those methods. Whether Iranian theocracy, apartheid (herrenfolk democracy as you say) etc.
Although I used to think it was hard to imagine a democratic variant of Fascism but I think as you say, that would be Herrenfolk democracy.
But for communism I think you end up with social democracy. Now people might protest against this but I think there are good arguments for this. Communist parties in China and the USSR never pulled of making a communist society. And that is not hard to see why. Communism as a system just isn’t possible in my view. You will forever be stuck in some transitionary state.
Communists in my native Norway and many other places looked traveled eagerly to the USSR to learn about their Utopia. What they found utterly horrified them. I look at communism as socialists who try to create socialism through armed revolution. Norwegian socialists realized from looking at the USSR that it was the wrong way and decided to pursue socialism in a democratic way. They never got to this end goal either but we ended up with social democracy. That is why I view the democratic version of communism as social democracy. It isn’t communism per say as such a thing cannot be made. It is simple the natural end product if you pursue that goal through gradual reforms within a democratic system.
Likewise I imagine you can develop a herrenfolk democracy through gradual reforms in a democracy because the powerful in-group will be able to keep winning elections. The problem is of course liberals and other factions within the in-group. That is why these people want race wars. They want to scare all white peoples towards their political ideology.
It is akin to how you may not have a choice but join the Nazis is a very brutal prison organized along ethnicity if you are white.
