Words do often suddenly get a new meaning but one not adjacent one that causes confusion. If a hat is “sick” nobody assume the hat has an illness. It’s just pathetic and it equates actual racism to stuff like people who think they are opposed for getting in trouble at work if they say the n word.

It’s basically moving the goal posts. Language is a malleable thing, however when one word is being already actively used by the majority of people for an adjacent meaning then a new word is needed. If people can’t use context other than the race of the victim to determine if you mean someone was racist or racist+ then your word sucks.
