The death of Catholicism.

[SofaKingHigh]

True enough. Nazism was not a religious phenomena, even if it had religious people in it.

My point is that even if the RCC wasn't responsible for the holocaust, and even if Priests and nuns tried to hide Jewish refugees, the Church (and Christianity generally) helped pave the way for it by dehumanizing Jews for so long.

Even if the Nazi/eugenics ideology wasn't clerical, the clerical antisemitism helped Germans and others "Get on board" with it IMO.

The Germans had a legitimate concern about the Jews being their domestic enemies.  The Jews had been trying for decades to overthrow the German government.  Guys like Herzl only gave them more reason to not trust them.  They wanted to install communism and when that slipped they did it in Russia, which led to subsequent decades of conflict with the West.  They continually urged the West to attack Germany, even going so far as to blackmail Wilson to declare war on Germany.  

Prior to WWII they instigated a world-wide boycott against German goods and services.  They wanted to wreck the German economy.  The Nazis wanted to deport all of them but some wouldn't  leave.  So the Nazis treated them as legitimate domestic enemies.    

As far as religion is concerned, remember what it says in 1 Thessalonians 2:14-16 https://www.biblegateway.com/passage/?se...ersion=CEV

The Jewish community boycotting German goods was in reaction to the Nazi's coming into power and their subsequent policies towards Jews, read up on your history.

"Install communism" - Do you have the installation instructions at all?

You sound dangerously like a holocaust denier.
