In my English class, we recently read an essay titled, "Nobody mean more to me than you and the future self of Willie Jordan" by June Jordan, and it talks about the same thing with Black English. It talks about how "standard/white english" (ever heard of “talking white”?) is seen as the only acceptable form of language in America and that is a problem with some people in racial groups because there are some words and dialects that are connected to their reality and identity. To say that the way they use language is wrong is to basically erase their identity and invalidate them.
In the same token, I see people of different minority groups judge each other based on how they talk. Like for example, people mocking some Latin americans for not speaking english properly, and some latin americans mocking the way some other groups speak. I’ve seen this frequently throughout school and in public, so I think this will be a hard battle to fight for this author. Maybe my realistic view can be seen as too pessimistic, but I think ignorance is part of human nature, and every group has their racism/bias and it’ll always be like this, the best we can do is minimize the pool of ignorance. I guess this is where the school can play a big role in making sure that more people in general become more informed that different groups of people are in fact...different and don’t express themselves the same way and that is ok. Like the author mentioned in the beginning, teachers sharing memes talking about identity and language being separate is something that they can change their understanding of, and then pass that understanding on to others at a young age.
In the meantime, "standard" english is still too dominant in this country, so due to standardized testing and job opportunities, it will still be important to teach the "standard" form of english, but maybe teachers can find a way to tell students that this type of language is not the only language that is valid in their lives. It's hard, but it's like a news reporter using their TV voice in their job, and using their real voices elsewhere.
