Not sure about the “artistic” part, but there’s a difference between a society being tolerant and being accepting. Society is tolerant of what she said. She hasn’t been lynched or tarred and feathered. She hasn’t been burned at the stake. And no, a private employee deciding to fire an employee because of socially questionable behavior does not approach any of those.
There is nothing that says a society has to accept the behavior. People have the right to be offended and act accordingly. If an artist decides to pee in a jar with a cross in it, people can be offended and not visit the artist or the gallery. If an “artist” says socially objectionable things, that same person can decide not to watch their show or the network that broadcasts it.
Our society is tolerant of opinions/“artistic interpretations,” but that doesn’t mean we have to accept them or the person conveying them.
