Sorry but I think that not doing what you can to facilitate communication with your interlocutor is impolite. Including not responding. Of course there is no obligation, but I'd find it impolite. I travel a lot, I have lived in different countries. If everybody tried to impose their local languages to foreign people, this would be impossible. Languages are tools for communication, using them as signs of identity is the arrogant part. By the way, calling Catalan an indigenous language is ridiculous.
