Well, sure, in that it's a word with lots of nonproblematic uses.
> It’s a legitimate dictionary word.
This implies probably a more normative role for dictionaries than is appropriate, but, sure, it is. However, as a noun applied to people (as distinct from the verb meaning “to slow down” or the noun meaning “a slowing down”) it’s one which every dictionary I can find flags explicitly as “offensive”, so insofar as one uses dictionaries as arbiters of usage, I think there clearly is a problem with the use of “retards” in question.
Maybe I’m a bad person, but this is my take. If someone uses the r word once in a while. Like it slips out when High school slang mode kicks in, I’m Okay. If it’s someone’s go to word, I feel that person is on the uncouth side of things. I’m not going to report someone to HR over it, or terminate a friendship, but I may minimize interaction with them.
But that goes for all excess vulgarity not just the r word. It’s not that I’m offended, but it’s a personal taste for less crassness.
