This happens in the West too. For example one of my favourite shows, "Peep Show" has a scene removed because one of the main characters wears black face to break social taboos. Obviously, it's done in a mocking way, but even mocking someone for black face has been deemed inappropriate by modern Western standards. The show isn't even that old either.
I'm almost certain there would be things seen as normal or inoffensive in China that would be seen as offensive and censored here. For example, a show that expressed criticism of homosexuality probably wouldn't be tolerated in the West. I'm guessing there could also be scenes that we would consider examples of animal cruelty given our differing views on animal welfare.
