The rhetorical point of reflecting the grandparent's use of language is to highlight that it's a meaningless argument, in reality. It's just fallacy to appeal to a limp as right to shut down an appeal to modern civility over regressive barbarity in our language.

The revival of eugenicist language is not a positive trend for any member of a disadvantaged demographic, regardless of how they wield their position in society.
