To qoute sources would be a worthless exercise. You would undoubtedly dismiss them as being 'distorted' and 'innacurate'. You and I can agree on that much. I do not have enough life left for such a tautological argument.
I believe, because of what I have read and because of Russian people with whom I have talked, that Stalin was a monster of such proportions that beside him Hitler and Pol Pot look like schoolyard bullies. You apparently believe something else. Neither of us could ever convince the other.
The bait you offer just isn't that tasty.
