I don’t know how else to say it, but: the unique aspects of the Holocaust are what makes the Holocaust unique.
Making up “tiers” of mass murder or genocide is dehumanizing. There is no point in trying to compare these atrocities - except of course if someone wants to say e.g. “Well, the holocaust wasn’t that bad”.
Even if that is “the propaganda” (which I have not seen in this thread btw): your counterproposition is not to dispose of the whole one-dimensional “which atrocity is worse” bullshit, but instead formalizing it by speaking of tiers and arguing that the holocaust wasn’t that bad. That’s dehumanizing, has no value at all (it’s not like a “tier 2 genocide” it somehow more okay) and instead opens the doors for Nazi apologia and antisemtism and derails the discussion.
