Coming from Sweden where they don't enforce this policy to the same extent (though it does exist) I think it's a good thing. Not being able to talk the same language as the local populace segregates the population and creates problems where there shouldn't be any.
Sweden got plenty of areas where Swedish is not the fist language. You got the samir people who has their own language. You got a Finish minority as well. Of course the Swedish gov cannot enforce this policy. That would be foolish to do so. Here click me learn something about your great nation. Sweden is a awesome place to be as a bilingual person. Sweden even acknowledge double citizenship, which has been a great thing for many fellow European citizens who worked, lived in Sweden and/or married Swedish people.
Oh and their is nothing wrong in being a patriot. Hence nazi != patriot. Patriots are allowed to like other cultures as well while the bad word mentioned before had some serious issues with democracy and human rights.
All I'm saying is that I think it's good that immigrants learn the language of the nation they move to. We get a lot of immigrants here that don't work and stay in their groups and never learn a single word of Swedish. Of course we get a lot of immigrants that don't, too.
Nothing wrong with being a patriot, no. But in Sweden it isn't something you say out loud. In some cases showing the flag or singing the national amthem can be considered rasist too. I'm sure you know of Rosengård. Try showing yourself there with the flag and you'll get lynched.
I know that area. I had a good friend living there for some time. He rarely saw any problems there. It is more like 100+ idiots making noise, throwing rocks at buses and burning garbage buckets down. They then see their actions on news in TV and feel proud. The journalists play along and give them what these bullies want.
Most of the people in Rosengård are friendly and mind their own business. Do not let wanna be gangsters bad behaviors change that fact. Also the people who find the Swedish national anthem to be an insult should need a good shrink as the lyrics is so soothing and peaceful. It could very well fit any Northern Europe nation
Then again wannabe gangsters often need a shrink
Oh and I have seen many occasions in Rosengård where a Swedish flag was used. No one would be lynched because of a Swedish flag there. Remember that many kids there celebrate their birthdays
