Note: in this piece, I am using the term, "designated group." That is because any grouping or lumping together of human beings is artificial. You could put people in a category of those with large nose size or of having type II diabetes. Yet, these are criteria that allow people to be put in a group, and it is based on the thinking of one or more persons. I hope that helps the following make more sense.
Historically and today, preliminary to pseudo-scientific abuse is to paint a designated group as subhuman. If we are speaking of people with disabilities, this perception may include depicting people as cute--e.g., "It was only a hamster."
Painting someone as sick or subhuman are tools used by an abuser to gain collaboration with peers in organized and systematic abuse of an intended victim, and in some instances it is sanctioned by governments, or at the very least, by organizations.
When people are put into categories, e.g., psychiatric "clients," they are considered objects of study and not human beings. This is a way of hiding behind the cloak of supposed science to subjugate and harm a designated group.
