>No, you are not going to get arrested in America for making a joke about George Washington.
If someone leaks you joking about repeating a historical terrorist attack the chances that the police at least pay you a visit is very high, in the United States and other Western countries.
There's actually a whole array of news articles you can find on your search engine of choice about arrests after people made social media posts about threatening politicians. Which I might add, joke or not is very reasonable.
and authorities don't know whether you joke or not, so this falls squarely into the category of "play stupid games, win stupid prizes", and again this is the same in the US. Quite a lot of people have been joked about killing Obama, and got a pretty quick visit by the police as a result. This isn't unique to China and there's nothing wrong with it.
