Thats a deep victim mentality. The examples you gave will not happen cuz people dont work that way, unless they're mentally weak and self entitled as hell. People change names, I've known some who did, and have seen examples of such. But they dont get 'sad' cuz someone called them by their prev names. In fact, if they're even a bit mature, they wont expect anyone to call them by their new names. Other people can try and change how they call such person, but then it would be a choice. Whereas here, we have people being forced to change how they speak to cater someone else's fragile heart.
