How does language correlate with identity?

In english class we are reading this article on Assimilation in America for Latinos. They are forced to Assimilate and learn English even though their dominant language is Spanish. The article was about how the author was an anchor baby and had been born in America but dominant language was Spanish. It also talked about her grandmother and she never learned any english and she spoke Spanish to everyone despite them not knowing it.

I don’t think people when moving to a new country should be forced to speak the native/dominant language of the country. They can be encouraged to do so but it shouldn’t be compulsory as some people have a lot of identity connected to their language.
