There is an opinion that knowing multiple languages expands your intelligence. Opposite applies also. And how do we call people refusing to learn even language of their own country?
You ask “how do we call people refusing to learn even language of their own country?”
We call them Hispanics in Amerika.
“...And how do we call people refusing to learn even language of their own country?...”
They do not object to learning the Ukrainian language academically but they do object to the language Gestapo. Take a name like “Anna” which should not be translated or transcribed differently if the citizen wants to be called Anna she should have that freedom. But all her documents and transcripts will have Ganna used instead of Anna as if Anna is subversive to the Ukraine.
