I don’t take offense, nobody is going to have exact lived experience. And open debate is much better than division. Your point about younger age group is valid, because it could be they used it extensively but were self aware and refrained in front of a slightly older person.

I saw same decline in the work place with a large swath of age groups. Many rough shop floor types use slurs still, but internal office and customer facing had a large decline in R word and homosexual slurs in my era.
But there is always one guy dropping it and the group goes quiet.
