Frankly, Goldberg is right. The Jews killed by Hitler were Caucasian people also.
Not that the Nazis weren't racist- they were as well. But the Jews were victims of anti-Semitism, not racism.
Race is technically defined by what type of skull you have. Heck, even many Ethiopians and Somalis are actually Caucasians (they have about 40% Caucasian ancestry, mixed with sub-Saharan African ancestry, but they inherited the Caucasian skull type.)
I guess it gives you special victim status to be the victim of racism?
Sort of like the absurd idea that being opposed to Islam is "racist."
