Having read "Down and Out in Paris and London" recently, I didn't notice anything too appalling. Just some stereotypical views of Jews, which I thought Orwell wrote with the purpose of describing a typical Brit from the early 20th century in order to criticize their antisemitism, but some googling suggests he expresses similar views in his diaries too, which is a bit more disconcerting.

> One could ignore this, just possibly, if it existed in a single book. And yet for 10 years the abstract figure of "the Jew" makes regular appearances in Orwell's diaries. Out tramping in the early 30s, he falls in with "a little Liverpool Jew, a thorough guttersnipe" with a face that recalls "some low-down carrion bird". Watching the crowds thronging the London underground in October 1940, he decides that what is "bad" about the Jews is that they are not only conspicuous but go out of their way to make themselves so.
