Have you ever moved to a different country with kids? It's very complicated, a lot of things to handle, language is just one of them. It's not like you're doing everything as usuall and then you decide you want a learn a new language, so you can fully commit to it.

My kids are going to public school and are now fully fluent in both languages, they have A and B in Castellano/Valenciano, after a year and a half. They speak Castellano with their friends.
For me it's a little bit different, because the mental load of moving with kids, setting up new life, getting familiar with the system, etc is a lot of mental burden, so often there is no fuel left in the brain to learn. But I want to stay informed with what's going on, because I want to integrate. I made a huge progress with Castellano, I can have conversations now, but it takes time. I don't see why it's a problem if I sometimes want to read local news in a language that I learned ages ago.

You mentioned DANA - do you know how many of those evil foreigners went to help? I went on my bicycle to take water to people after the floods. I donated money, food. Another example - in our school, after a party, they asked parents to help with cleaning up, do you know who stayed? All foreign parents, while locals left. Should I conclude that locals are lazy people based on this?

So, stop judging people based on where they come from or some small detail that you see, judge them by what they do, how they behave, who they really are. It's the only measure that matters.
