So the best the libertarians can come up with are a couple of anti-Semitic lines? Weren't most people anti-Semitic back then? I thought you guys had legitimate attacks against you know, his economic theories.

Keynes was an undoubted HP. He was director of the British Eugenics Society from 1937-1944 and defended those ideas until his death in
1946.
Of course talking about his eugenic ideas in the context of his economic theories is equivalent to thrashing Newtonian physics on the basis of Newton's notorious interests in the occult.
