I tried to avoid wading into the "Is Jewish a race?" debate or haggling over which race Jewish people belong to, which I won't do here in the comments either. I will leave the demographic particulars of the global Jewish population to experts like you. Race is a man-made construct that seems to be forever changing (when I was a kid - and, I presume, at the time of the Holocaust - there were three; now, according to the US census, there are five), so I think it's pretty pointless to get bogged down in that discussion. The overall point I wanted to make, which I believe I did, is that whether you consider Jewish people to be White or whatever, the Holocaust had everything to do with race.
