Their numbers killed were higher...but that was because they mostly were in power longer than Hitler. No one ever made a “boy scout” out of Hitler...the Holocaust alone stands out in the annals of history for it’s nightmarish thoroughness and endless cruelty...it was unique even amongst other genocidal crimes.
You make a great point. I hate the discussions of who was less bad - Hitler or Stalin? Hitler did an incredible amount of destruction in just 12 years. And he spent the first 5 years consolidating his power and ramping up the terror and the killings. A comparison of what communist and fascist dictatorships have in common would really put the leftists in their place. Instead, such discussions turn into some twisted argument that Hitler was “less bad” than some communist, based on how you calculate the body counts.
