Stalin didn't speak breathlessly about the "triumph of the Aryan race" or how the Indians inflicted famine on themselves by "breeding like rabbits". In fact, in the latter case, Stalin used both his executive power and personal sway to expedite aid to Bengal.

Stalin can and should be criticized (e.g. he was deeply homophobic from what I can tell), but drawing an equivalence between him and a monstrous colonialist and racial supremacist like Churchill is frankly disgusting.
