So Anyway

Marx was a raving antisemite. Old school Progressives (the one they NEVER teach you about in the public schools) had "issues" with those they saw as the "inferior" races. (Africans, Jews, Asians, etc.) And eliminating those who don't fit into the collective makes perfect sense to a collectivist.  I've come to the conclusion that anyone who sees another person as either a tool to be used, or as trash to be disposed of, is essentially a Leftist. (Which pretty much puts me to the right of Attila the Hun.)
