Christian ethnic cleansing of Jews? What exactly are you referring to?
Would that be the pogroms of Phillip II of Spain? Surely you aren't referring to the Nazi Holocaust??!! If even YOUR ... expanded ... vision of Christian liability extends that far, then every evil committed anywhere in the universe can be laid at Christianty's feet.
There was nothing CHRISTIAN in the Holocaust. Just because the Nazis were not Jews doesn't mean they were Christians. In fact, their Gothic heroic model came much more from the pagan tradition than from anything Luther taught.
Sheesh!
