Right. It is not one-dimensional. Each nation has its own evil genius. The German nation had the gas chambers and the Russian nation had Kolyma and Holodomor. May we never know what American evil genius is. To say that one method of killing is one a separate plane compared with others is to deny the other evil.
I reject that completely.
They are each on a separate plane compared with others...a separate plane of their own uniqueness.
There are aspects of evil in the Holocaust not inherent in the GULAG system: systematic industrialized extermination, based on religion/race.
