“Racism is simply an ugly form of collectivism, the mindset that views humans only as members of groups and never as individuals. Racists believe that all individuals who share superficial physical characteristics are alike; as collectivists, racists think only in terms of groups. By encouraging Americans to adopt a group mentality, the advocates of so-called 'diversity' actually perpetuate racism. Their intense focus on race is inherently racist, because it views individuals only as members of racial groups. Conservatives and libertarians should fight back and challenge the myth that collectivist liberals care more about racism. Modern liberalism, however, well-intentioned, is a byproduct of the same collectivist thinking that characterizes racism. The continued insistence on group thinking only inflames racial tensions. The true antidote to racism is liberty. Liberty means having a limited, constitutional government devoted to the protection of individual rights rather than group claims. Liberty means free-market capitalism, which rewards individual achievement and competence, not skin color, gender, or ethnicity. In a free market, businesses that discriminate lose customers, goodwill, and valuable employees- while rational businesses flourish by choosing the most qualified employees and selling to all willing buyers. More importantly, in a free society every citizen gains a sense of himself as an individual, rather than developing a group or victim mentality. This leads to a sense of individual responsibility and personal pride, making skin color irrelevant. Rather than looking to government to correct what is essentially a sin of the heart, we should understand that reducing racism requires a shift from group thinking to an emphasis on individualism.”

Context: I introduced an amendment last week that would have eliminated funds for this intrusive survey in a spending bill, explaining on the House floor that perhaps the American people dont appreciate being threatened by Big Brother. The amendment was met by either indifference or hostility, as most members of Congress either dont care about or actively support government snooping into the private affairs of citizens. One of the worst aspects of the census is its focus on classifying people by race. When government tells us it wants information to help any given group, it assumes every individual who shares certain physical characteristics has the same interests, or wants the same things from government. This is an inherently racist and offensive assumption. The census, like so many federal policies and programs, inflames racism by encouraging Americans to see themselves as members of racial groups fighting each other for a share of the federal pie.

Context: Only through the group, I realised — through sharing the suffering of the group — could the body reach that height of existence that the individual alone could never attain. And for the body to reach that level at which the divine might be glimpsed, a dissolution of individuality was necessary. The tragic quality of the group was also necessary, the quality that constantly raised the group out of the abandon and torpor into which it was prone to lapse, leading it to an ever-mounting shared suffering and so to death, which was the ultimate suffering. The group must be open to death — which meant, of course, that it must be a community of warriors.

Context: Speciesism is an attitude of prejudice towards beings because they're not members of our species, so just as racism means that you're prejudiced against beings who are not members of your race and sexism means you're prejudiced against people of the other sex. So we humans tend to be speciesist in we think that any being that is a member of the species homo sapien just automatically has a higher moral status and is more important than any being that is a member of any other species, irrespective of the actual characteristics of those beings.
