Language can unify or divide us

Yes, I do agree that language can unify or divide us. For examples: English is the one of many commonly used languages in the world that allows people work together in any international areas. If Obama comes to my country or other Asia countries, he and the governors will use his English to work together or even they need translators but they are basic on English. However, English can divide us also because there is discrimination about language and the culture that the language belongs to it. In my country, if someone can speak influence English, they have admiration from people around them but they also get the ridicules from conservative people who just know only their native language. Today, many young generations were born and grown up in American, and most of them lost their mother language and had a strong English. Their grandparents or parents, who were lack of English, had a difficult time to teach them about their tradition culture or the native language. In this case, there are the speaking different languages and opinions cause the big distances in the family relationship. Therefore, language can unify or divide us.
