I want to know the answer to the following question:
Towards which social topic did the Cubists  at the Salon d'Automne creat contrevesy towards?
All the background I'm provided with is that "The controversy spread to the Municipal Council of Paris, leading to a debate in the Chambre des Députés about the use of public funds to provide the venue for such art.". Is that enough to answer the question?
Answer: no
