Not that Wikipedia is authoritative for anything, but it describes one of those words as “a term, usually considered a slur, used to refer to gay men.” I would personally characterize the r-word as a slur if referring to an individual with an intellectual disability (and at least as in poor taste otherwise). I’m over 40 so do not understand “based.” Of course, one can disagree with these opinions, but it would not be unreasonable for David to have characterized some of these words as slurs.
