I’m old enough to remember when Hitler personified incomparable, bottomless, merciless evil. These days he’s mostly used by the left as a cudgel to hammer, ineffectively, Donald Trump. In doing so, Democrats risk trivializing and even sanitizing Hitler.

What sets Hitler apart from other monstrous 20th century dictators — such as Mao Zedong and Stalin — was his all-consuming Jew hatred, his unprecedented Jewish murders, his factories of death and extermination that slaughtered 6 million Jews.

Mao and Stalin (himself an antisemite) each killed more people than Hitler, yet the German fuhrer is recognized as the worst tyrant. The reason is clear — the Holocaust.

There have been other genocides, such as those of Turkey against the Armenians and the Hutus against the Tutsis in civil war in Rwanda.
