I think it occurs someone criticizes a political opponent for using a word or phrase which has been commonplace until that time, though some may have considered it offensive. Immediately, that usage is widely decried as horribly offensive, and even groups that routinely used it pile on to join the attack: "When (my opponent) said X today, it shows they are horrible and intend terrible things, whereas my use of it yesterday/last year (or in the future!) was completely innocent." The direction of the politicization will remain in dispute: Did my opponent politicize it by using language known to be offensive, as a callout to their constituency? Or did I politicize it by criticizing them, as a callout to my constituency? Or do they politicize it by continuing to use it afterward?
