Need to refute Malthus?

"Malthus, a man who, not to put too fine a point on it, was the scum of the Earth, who thought poor people should be deprived charity and healthcare and if they died as a result, well good, since they have ‘no claim of right to the smallest portion of food’." That Malthus? Well, you could do worse than this article. What interests me about Malthusianism is that someone could run theories that are empirically disproven, and get away with it. You've got to love debate: Tabula rasas gone wild!
