I think that I will pass on this talk. Stalin was not a powerful human. He was one of a handful of the least human human beings that our species has had to experience and to endure. If a talk is to be about Stalin's regime, it may be best to omit him entirely and to share of the experiences of individuals and/or of their families that had to endure and/or who had survived the crimes against humanity that Stalin was the architect of. There is nothing powerful, redeeming, nor worth talking about when it comes to Stalin.
