The right.

Hmm, the internet seems to think Swarthy just refers to olive-skinned people with, sometimes, the added characteristic of being weather-beaten. Some mention of pirates and worthiness, but not a mention of anything to do with the Jewish people except the image Fake Messiah has was one of the images when I searched for Swarthy.

Oh well, that's OK then.

The blatant anti-Semites who use the word to describe a Jewish painter are just thinking about complexion. 

(I met Rothko's kids once. They are not more olive-toned than I am.)

If you Google "oily" it probably won't mention anti-Semitism either, but it was still a word commonly used to describe Jews in older literature.
