The UK has definitely seen it before!
This is the same confusion I have when someone decides to boycott a movie based on an actor. It's very likely some of the hundreds of people who make most movies are awful too, it's entirely futile.
We only seem to care when the person who is bad is also famous. I think everyone else is just as apathetic, but deludes themselves. I promise you that most things you own or use have some tier of evil within them. People buy cheap clothes, slave made phones and all sorts of things all the time and elect to ignore the imorality of it.
