According to Richard Rodriguez, how can language define community – both negatively and positively?

Negatively

Explanation: Rodriguez defines it as a way that communities get separated, such as the instances where he feels that his family is isolated from the English speakers in his neighborhood, and how the other kids will stare at him and not interact. Positively, it is a way to bring people together of similar languages. He and his family have fun, laughing together, when they are home, because that is a place where they are free to speak Spanish to one another, free from judgement.
