I am so glad you posted this. Sometimes I get into little arguments about word usage and younger folk truly don't understand how not only commonplace word usage that is considered some sort of insult now but how officially they were used. Near me was a place that helped folks with all sorts of independent living including housing and job training and just counseling and it was called the NSAR and Im almost sure the R was retardation. Think it changed its name and I can't find anything on it now but I did find like this https://mn.gov/mnddc/parallels2/pdf/70s/70/70s-WWH-NARC.pdf

Disney’s Recess was censored to remove the term midget

Apparently now little person/lesser human is the preferred term

I find it hard to believe lesser human would be used as a term. Its a bit funny because again midget was also used as opposed to dwarf by the relative proportionality even though dwarfism was appropriate for both types. Was it being used to describe someone in the show with dwarfism though because if not then it was sorta being used derogatorily.
