It's fine to live somewhere for many years without learning the local language. Even learning a relatively "easy" language, like German for a native English speaker, takes about a year of full-time dedication. Not everyone has time for that.
It's definitely not ok, however, to act as if you're an expert about the local culture. There is so much you can't grasp unless you speak the native language. Talking to people is important, but equally important is consuming native media and the news.
