The person who does not understand is you.
I told you I'm learning Japanese, not because you told me to, but to show you, hey wait, it's possible to learn a language which is entirely different from your own!
Yes I know it's not easy, but it is possible. Learning English will maybe make things a lot easier for them if they ever leave their homeland, and a lot easier for other people who try to have fun on the same playground as them, too.
That's the other thing you don't understand:
I'm not saying "Oh my god! How dare they do not learn English, ignore them, bash on them, whatever!"
What I'm trying to say is that it's basic politeness to try being able to communicate with others, even if they do not speak your native language.
You can get by without being polite, but the other person will always feel kind of bad, and that's the reason why threads like this one are made.

Generalization:
It would be a generalization if I ever said that all people speaking in their native language are always like that. That's the definition of that word.
I never did. All I said is that things like that happened to me. I described what I experienced. Where do you see a generalization?

"Taking something for granted" means to think of certain circumstances as the norm, although they may not be the norm.
Well, I never said it is. All I did was expressing my wish to have people around the world who all speak at least two languages: their own and English, so they con communicate with people from other countries too. It's something like..a vision of mine. What's so bad about having a dream where everyone can just talk to anyone?
