I agree that the confusion stems from the words Down and Syndrome when said together. It can easily seem to sound like Downs Syndrome, or Down's Syndrome, as heard, when the term is spoken.
However, Lacy explained to the FB poster that it is Down syndrome, and the poster still argued with Lacy.
About Derpy:
Derpy Hooves, a pegasus pony, is a fictional character in My Little Pony, Friendship is Magic (a TV series?)
http://mlp.wikia.com/wiki/Derpy
The pony was named Derpy, because of its crossed eyes.
The Urban Dictionary offers various definitions of derpy, including: clumsy, uncoordinated, accident prone, awkward, lacking intelligence or common sense, and yes, the R-word. One person wrote that derpy "usually takes the place of 'retarded.'"
http://www.urbandictionary.com/define.php?term=Derpy
Given that definition, as it is used to substitute for the R-word, it's a substitute slur. R-word is the brand name; derpy is the generic.
And how sweet -- for our children to be watching cartoons using this word to denigrate a clumsy, cross-eyed pony. Hasbro adopted it with pride! And now the young generation will grow up with their stuffed Derpy toys, using that name, with the same belittlement contained in the R-word.
My frustration is enormous to discover that after fighting against the use of the R-word for over 40 years, a new replacement word, with the same intention, has been introduced. We can't change attitude, if we don't change behavior. Frankly, I'm tired of trying. This makes me want to give up, but I won't.
I can't.
Love & Light,
