I want to know the answer to the following question:
Was Duchamp's work considered controversial when displayed in 1912?
All the background I'm provided with is that "Although the work was shown in the Salon de la Section d'Or in October 1912 and the 1913 Armory Show in New York, Duchamp never forgave his brothers and former colleagues for censoring his work.". Is that enough to answer the question?
Answer: no
