'Karl Marx was the foremost hater and most incessant whiner in the history of Western Civilization...'

From Gary North, Marx's Religion of Revolution: Regeneration Through Chaos:

Karl Marx was the foremost hater and most incessant whiner in the history of Western Civilization. He was a spoiled, overeducated brat who never grew up; he just grew more shrill as he grew older. His lifelong hatred and whining have led to the deaths (so far) of perhaps a hundred million people, depending on how many people perished under Mao's tyranny. We will probably never know.
