I agree that they are all on a separate plane, and that the gas chambers are the synthesis of the specific evil of the Holocaust.
But you just did something very similar to denial of the gas chambers by Williamson: you denied the extermination aspect of the Gulag based on a book that you read. Does it cross your mind that perhaps Hannah Arendt’s book has been likewise rebutted? I could probably cite from Lenin, Trotsky and Stalin regarding their intentions as they formed the NKVD.
Arendt explains it, but her work is not the basis of my denial.
GULAG is plainly NOT exterminationist. They were work camps.
Are you aware of any facilities in GULAG designed for industrialized extermination? Any evidence that there was such intent?
I'd like to see evidence of some kind of Soviet Wannsee Conference, though I doubt any such thing exists. GULAG did not undertake to merely kill, as rapidly as possible, through the skillful application of modern efficiency. It was a hybrid of political imprisonment and slave labor.
In light of his various statements (including his denial of gas chambers at Auschwitz), my original point--that Williamson was/is a Holocaust denier--would thus seem to be demonstrated.
