The great Heather MacDonald has a brief column on political correctness at the CDC:
The public-health establishment has unanimously opposed a travel and visa moratorium from Ebola-plagued West African countries to protect the U.S. population. To evaluate whether this opposition rests on purely scientific grounds, it helps to understand the political character of the public-health field. For the last several decades, the profession has been awash in social-justice ideology. Many of its members view racism, sexism, and economic inequality, rather than individual behavior, as the primary drivers of differential health outcomes in the U.S. According to mainstream public-health thinking, publicizing the behavioral choices behind bad health—promiscuous sex, drug use, overeating, or lack of exercise—blames the victim.
