I don't think we should shame people for not speaking the language of the country they live in, however it's important to stress that you're really missing out when you don't speak the local language.
It will vary a lot by countries, because in some of them (i.e. northern european countries) everyone will be able to speak English so not only you have less incentive to learn the local language but it will be very difficult to practice because the local won't make the effort of speaking to you in their language until you're good enough (which you're not because you lack practice).
Speaking of Japan, as someone who lived there for a few years and reached a decent Japanese level, the English proficency of locals is not great so if you don't speak it you'll be stuck in your bubble of foreigners + Japanese people used to hang out with foreigners. I've seen a lot of foreigners not speaking Japanese after living several years in Japan, and most of them were wonderful people but they were like permanent visitors in the country they live which I thought was really too bad.
I think we should shame people for that: A nation is like a big family. You're essentially saying that you don't think that you should be able to talk to your own family in their language.
It’s not only that. It’s just more work communicating with someone in your non-native language. Especially in Japan where many people don’t speak English well. So you’re creating an additional burden on the people around you.
And that absolutely should be shamed, especially when you’re talking about a society like Japan that places high value on individuals acting in ways that make things easier for people around them and society at large.
I don't think this sentiment would go over so well if I expressed it to people here on the West Coast of the US. Not to mention that there are people that will send their kids to bilingual schools for (and this is conjecture) either lefty political points or potential socio-economic reasons (dual language or Chinese immersion).
I personally love learning languages and am that person that tries to learn a little bit and communicate wherever I go. I does seem to be a hot button issue here in the US. I think people have different expectations. You hear stories of immigrants from the early 20th century that would force their kids to only speak English so that they would get on well in society. It seems like a difficult topic here around heritage vs managing in a society, especially for kids.
