I had recently read an article about forced language assimilation.It was written by a person whose parents were Spanish immigrants in the United states but had become citizens in due course.The article-https://www.theguardian.com/commentisfree/2015/sep/10/donald-trumps-fear-spanish-power-language-identity
The journalist in the article, feels that forced assimilation requires policing people’s language and that it is liberating and empowering to not give into it. She also feels that forced language assimilation is oppressive.She believes that getting rid of your accent means giving away your identity, If someone tells us to get rid of this identity, they are indirectly telling us that our voice does not matter, that we are powerless.
The journalist speaks English but her mother tongue is Spanish. Early on she had tried to assimilate as well, as she wanted to feel a sense of belonging. In my opinion, we should try and learn a new language if we have got a chance to. Learning a language can help foster a better appreciation of the culture and ease communication with the locals. But no one should be forced to communicate in a language. The language learnt could just stay as an extra, secondary language.
But having said that, lets consider, “Why do we judge people who speak broken english?”
