Let us leave aside the fact that the Justice has just favorably compared SCOTUS to Hitler in order to dwell on a fact he may have missed: to whit, Catholics (including the Pope) and Christians in general didn't just resign. They actively tried to assassinate Hitler and his minions. And frequently succeeded.
So, if Justice Kennedy wants America's Christians to emulate the Christians who lived under Hitler's regime, I am sure we can accomplish that. Remarkably, Justice Kennedy certainly appears to be giving his blessing to the endeavor.
