The Centers for Disease Control and Prevention’s Healthy Communities Program, for example, focuses on “unfair health differences closely linked with social, economic or environmental disadvantages that adversely affect groups of people.” CDC’s Healthy People 2020 project recognizes that “health inequities are tied to economics, exclusion, and discrimination that prevent groups from accessing resources to live healthy lives,” according to Harvard public-health professor Nancy Krieger. Krieger is herself a magnet for federal funding, which she uses to spread the message about America’s unjust treatment of women, minorities, and the poor. To study the genetic components of health is tantamount to “scientific racism,” in Krieger’s view, since doing so overlooks the “impact of discrimination” on health. And of course the idea of any genetic racial differences is anathema to Krieger and her left-wing colleagues.

Local public-health programs are just as committed to “social justice.” The National Association of County and City Health Officials promoted a seven-part PBS documentary, Unnatural Causes: Is Inequality Making us Sick?, to trigger community dialogues about health equity. NACCHO’s Health Equity and Social Justice initiatives seek to “advance the capacity of local health departments to tackle the root causes of health inequities.”

During the height of the AIDS epidemic, the public-health profession abjured any focus on abstinence as a means of stopping the spread of the disease. This silence was contrary to decades of public-health response to venereal disease, which stressed individual responsibility, as well as contact tracing, to prevent further infections.
