Karl Marx (yes, I know he was of Jewish ancestry) wrote some of the most horrendous anti-Semitic propaganda ever penned, but somehow that hasn’t led the world’s Jews to repudiate Marx or socialism.
Yes, I have a book called the Tangled Bank (I think, by Stanley Hyman) which features some of Marx’s more lurid descriptions of Jews. You need tongs to read it. Those writings don’t get too much play in either media or history, do they?
