If you don't like it don't book tickets is not enough, it's ok to feel outraged at something so despicable. In fact, we should be complaining about this, not just ignoring it
This is exactly what peopleare complaining about with "cancel culture"!
I don't like this so it should be cancelled, I think this is bad so it shouldn't be allowed...well guess what, nobody asked you.
If we cancel everything someone finds offensive, there will be nothing left. There have always been plays, musicals, books, films etc about all kinds of things, many of which you may not personally like. But it's not for you to decide what plays people can put on and what plays people can watch.
It's for society as a whole to decide what is acceptable, the likes of Roy Chubby Brown and Jim Davidson don't get TV time anymore because society en masse decided they weren't acceptable any more, that's how it works. Not because outraged individuals screeched about how offensive somehting they haven;'t seen is.
No, of course it shouldn't be stopped. It's a free country and if enough people think its not ok, they won't sell tickets and it will disappear.
