More surprisingly , there is not a single mention of the most important public event for Degas during the 1890s , the Dreyfus affair , when Degas didn 't just look like a dog but behaved like one , cutting off Jewish friends of long standing and adamantly insisting ( along with Paul Cezanne and Renoir ) on the guilt of the Jewish army officer falsely accused of treason .
Degas is viewed as a traitor by Jews , because he cut off his Jewish friends , even though he did it for good reasons .
