This company has published content supportive of white nationalism and white supremacy. "Human biodiversity" (HBD), an alt-right euphemism for scientific racism, was one of the main publishing subjects of Washington Summit Publishers. The Southern Poverty Law Center (SPLC) said in 2006 that the company had reprinted racist tracts along with books promoting antisemitism and eugenics. In 2015, the SPLC listed Washington Summit Publishers as a white nationalist hate group.
