Why would I doubt Stalin? LOL!
Your losing track of the debate. You claimed that Stalin rejected Darwin, not that he -- or Lysenko -- misunderstood him.

Weikart is a fellow of the Discvovery Institute and an avowed opponent of evolution. He's spent his career attacking 'Darwinism'. Why would I take him as an authority on anything?

You believe Hitler.
But what motive would Stalin have to lie about the source of his atheism?
