Above all, population control programs are racist. Just as the global population control program itself represents an attempt by the (white-led) governments of the United States and the former imperial powers of Europe to cut nonwhite populations in the Third World, so, within each targeted nation, the local ruling group has typically made use of the population control program to attempt to eliminate the people they despise.
How did it begin?
For too long, there has been a single ideological current running through a seemingly disparate collection of noxious modern political and scientific movements, ranging from militarism, imperialism, racism, xenophobia, and radical environmentalism, to socialism, Nazism, and totalitarian communism. This is the ideology of antihumanism: the belief that the human race is a horde of vermin whose unconstrained aspirations and appetites endanger the natural order, and that tyrannical measures are necessary to constrain humanity. The founding prophet of modern antihumanism is Thomas Malthus (1766-1834), who offered a pseudoscientific basis for the idea that human reproduction always outruns available resources.
