Thoughtful people interested in learning more about how the Nazis are part of the Left may be interested in seeing the very important movie "The Soviet Story"
The Soviet Story (2008) - IMDb
(Parental advisory: although the link above to IMDB is safe for all, the documentary movie "The Soviet Story" is a VERY graphic accounting of many of the Left's innumerable atrocities against Mankind, and so is not appropriate for very young children. I'd recommend that concerned parents view it privately.)
They incorporate both left and right. Hitler's claim to the orb, scepter, crown and sword of the Holy Roman Empire wasn't very leftist.
