I just like the idea that immigrants are encouraged to learn and talk the new language as often as they can. It only benefits them.
But that's at least two ideas:
1) "Immigrants are encouraged to
learn the new language, it only benefits them."
Yes, of course it only benefits them. But it's not like if the immigrants couldn't come up with that idea themselves. I also don't get the sense of writing encouragements like this into political programs apart from pandering to resentments like "Immigrants don't want to integrate, they have to be told to do so".
2) What the CSU actually said is "Immigrants are encouraged to
talk the new language
as often as they can."
a) This totally neglects the value of multi-linguality and gives the idea that one can only be good at one language or the other.
b) It's again about telling other people what to do, mandatorily or not. (Same holds for those who want to abolish dialects.)
