Slovokian priests, dressed in their livery, loaded slovakian jews up for the camps for Hitler's ovens. Followed by confession, and mass absolution. German and Austrian catholic churches collated and delivered their birth and death records to the SS, to help ferret jews out of the general population--something they were able to refuse to do, when it came to jews who had converted to christianity. Is that contemporary enough for you?
And was this... religious in nature? Or did the descent of man (and it's lineage) have anything to do with this?
