Ulysses was written in Paris, where James Joyce lived, and was published in Paris by the now legendary Shakespeare & Co. The US and UK banned it for being obscene.
When I don't know, I ask and don't judge (and lacking omniscience, I don't judge anyway).
It's completely irrelevant where it was written, where it was published and where it was banned, I'm talking about how it is seen today. It is possible I am getting this wrong -certainly possible, since I'm taking this impression from English speaking sites like this, that I attribute to the US what should be attributed to England -, but I have seen no argument so far that even strives the point I made.
