As far as i was taught, and has held true, he was a Jew.
Defining someone as Jewish according to bloodline is exactly what the Nazis did in their notorious Nuremberg Laws. It set the stage for a genocide of millions.
Plus, one's bloodline alone does not necessarily influence one's ideology, especially in the case of Marx, whose writings obviously show contempt for that bloodline.
Dear justiceseeker,
re:
“Defining someone as Jewish according to bloodline is exactly what the Nazis did in their notorious Nuremberg Laws” (I still say he was a Jew.)
What about all this ‘ancestry dot com’ nonsense?
In this time and date, would that not describe how ‘the family name’ has always been defended, until the last few decades? Family inheritances by bloodline? Family succession by bloodline ... wasn’t that one of the stipulations in the feudal codes?
Bi-racial kids ending up with sickle cell anemia, Barr-Epstein, and other peculiar anomalies previously identified as residing within certain racial groups, alone?
And for the record, there are only 3 (three) races, Caucasian, Negroid, and Mongoloid. (For example, mexican is not a race. it is a nation.)
