Unlike Judaism or Islam, one is not born a Christian merely by being born into a family of professing Christians. Being baptized or answering an altar call does not make a person a Christian. The actions of the Nazis or the pogromists of Tsarist Russia are sufficient evidence to cast doubt on any claims of such people being Christians even if they were regular churchgoers. That there was rampant anti-Semitism in central and eastern Europe in the late 19th and early 20th Centuries cannot be doubted. Also not in doubt are anti-Semitic statements made by Catholic, Eastern Orthodox, and Lutheran clergy at that time. However, their statements were clearly un-Scriptural, as God stated that He would bless those who blessed the Jewish people and curse those that curse them (Genesis 12:3, Genesis 27:29, Numbers 24:9). These clergy were CINOs as much as Abraham Foxman is a JINO.
Might you agree, then, that part of the problem here is that, although Hitler was clearly not an "operational" Christian (your kind), he did use Christian-derived (to distinguish it from truly Christian) memes? And that makes many Christians itchy.
second reply:
My defintion of a Jew is anyone who Hither would have had killed as a Jew.
I am aware of the Jewish definition as a person with a Jewish mother.
