Are changes in language directly related to the power of a group of language users?

I read a status on Facebook during break about Harry Potter that used the word muggle. It reminded me that muggle is now an official word in the Engligh language. This word was used by many after the books were published. It makes me believe that changes in language are directly related to the usage by the majority. Words will not be added or removed from the dictionary unless the majority of the speakers agree with the changes. That's why muggle was added to the dictionary. Harry Potter was and remains very popular  The majority of speakers knew what the word meant and would use it. If anyone in the future ever wants to make a major change to a language, they must get the support of the majority of speakers.

Does language define our identity?

I am a big rap fan. Over break, I've been listening to Common's new album, The Dreamer, The Believer, a lot. The production is very strong, and the lyrical content is deep and meaningful. I think language used absolutely defines our identity. I immediately associate Common as a very intelligent person. Fair or not, that is how I see him. On the other hand, I cannot take someone like Lil Wayne seriously. He is not able to use language in the same way as Common, and comes across as stupid. This does not just apply to music, however. I believe we all, to certain degrees, will take someone more seriously if they come across as coherent and inelligent. We see them this way based on the way they use language. If someone does not do this, we may not appreciate their ideas fully. Language definately defines our identity.

Should governments have a language policy for a particular nation?

One of the big debates happening in Ameican politics right now is the role of government. How muchpower should they have? Should the government be able to restrict what we do? This made me think about language. Should a government be able to force a language policy on its people? To me, the answer is no. I do not believe that the government has the right to enforce it. Take America, for instance. Do I believe that it would be in the best interest of people who do not speak English to learn it? Absolutely. However, they should not be forced to learn it. If this were to happen, some minority languages might become extinct in certain countries. Also, many languages are a reflection of culture. If language is restriced, then culture might also be restricted. Finally, there would be no reason for anyone to learn other languages. This would be unfortunate, as we can connect with others better when we understand their language and culture. A government should not enforce a language policy.
