In an earlier post I had given this post. If you would check, you would find that this wasn't just for for mentally handicapped. It was also for the
"Native Americans" and the French-Canadians.

Groups Targeted and Victimized
Poor and socially ostracized families were targeted for investigation of the three D’s (delinquency, dependency, and mental defect). These families
usually lived “outside the accepted moral or social convention of middleclass America” (Gallagher, p. 37). The three D’s were used to target the
poor, the disabled, French-Canadians, and Native Americans. Women were targeted more than men. French-Canadians and Abenakis were seen as a foe and
threat to the early colonial settlers of Vermont. They represented “an insidious and continuous invasion” of Vermont and were therefore targeted
(Gallagher, p. 45). Studies done on degenerate family lines were often traced back to French Canadian or Native American ancestry and were used to
target these groups (Gallagher, pp. 80-82).
Families who were notorious for having illegitimate and/or "defective" children were targeted, as were those notorious for illiteracy, incest, and
for having institutionalized family members (Eugenics Survey in Vermont: Studies). Families that had "bad heredity" or mixed racial ancestry were
targets of Vermont's Eugenic survey.
Interestingly, as it was historically believed that the French had interbred with the Abenaki, the prejudice against these two otherwise-disparate
groups was in fact linked.
