Listening to liberals praise Mao, casually discuss a woman’s “right to choose”, and defending the Palestinians, I have no problem whatsoever understanding how the Holocaust happened. People commonly have a blindspot to slaughter that is out of sight, especially when it’s influenced by political dogma. The SS just loved their ‘Dear Leader’ without reason or restraint.

We have indeed descended into a culture of death.
