I just read with interest an AP news report on discussions in Maine about updating standards to include teaching about the misapplication of science in middle school science. According to the AP: 

• The proposal states that science education in the state should reflect that “misinterpretation of fossil observations has led to the false idea of human hierarchies and racial inequality.” The proposal also states that “historically, some people have misused and/or applied the ideas of natural selection and artificial selection to justify genocide of various groups, such as Albinos in Africa or Jews [and, I would add, people with disability] in Europe.”

This reminded me of a Maine Public Radio 90-second long piece from November, with a quote by an archaeologist professor emeritus of environmental science and policy at the University of Southern Maine about the addition of Malaga Island, which was once home to a mixed-race fishing community, to the National Register of Historic Places. According to the print version of the piece (with link to audio):

• "Located off the coast of Phippsburg in Casco Bay, Malaga Island was first settled by several Black families in the 1860s. Additional Black, white and mixed-race families would build homes on the 42-acre island in the following decades.
• "But the state forcibly removed Malaga's residents in 1912 in a decision tied to racial prejudice, the eugenics movement and social tensions with wealthier coastal residents who disapproved of their poorer neighbors across the water."

I have been looking for Library of Congress resources specifically addressing pseudo-science, Eugenics, purity contests at state fairs, and the like in Maine, so far without success. Perhaps others with more knowledge can add links to primary sources to make this a richer discussion.
