Huh. Maybe I don't understand the question.
When people can express themselves as they choose, that is Freedom of Speech. If people choose not to express themselves in a way that will offend others, not only is that still Freedom of Speech, but in other contexts it's called Getting Along With Other People.
I don't call black people by the so-called "n-word" because it's considered offensive. This isn't a violation of Freedom of Speech -- I freely choose not to use that word because I sincerely don't want to offend other people in this manner.
But when people have to be careful of the way they express themselves because of threats or intimidation, then that is no longer Freedom of Speech.
