F.A. Hayek tells us why people try to deny the similarities between what’s happening now and what happened in pre-Nazi Germany.
People compare themselves now with how Germany ended up - a genocidal regime bent on world conquest - and can’t, due to the extremity of the evil of the German regime, see that our society could ever end up there.
This is why you have to do things like give a description of the political, economic, and social climate in the era leading up to the atrocities, without mentioning the era or the country, and ask the person you’re talking to to identify the situation you’re describing - THEN tell them it was pre-Nazi Germany.
Unfortunately, rather than being bent on global conquest, Hussein is running a regime determined to destroy the United States and surrender to Islamists.
