Should Writers Use They Own English?

For this essay I had a lot of trouble reading it smoothly for obvious reasons. I think for certain people it was probably easier to read that essay because they are used to talking or using sentences like that but not me. Don't get me wrong I definitely don't talk outside of school exactly how I do inside the school but I believe the difference is not much. I think I understand his argument pretty well and maybe its unfair for me to say that I don't agree with him because I don't talk like him but I also believe that his argument has flaws. "Fish got it wrong here. When were talkin bout so-called varieties' of English or dialect in relation to standard English, we're not dealin with two different languages; we're dealing with a common language." In these sentences Young is critiquing Fish's advice where he says "I am not here to take that language from you; I'm here to teach you a another one." I believe that Young is actually the one that got it wrong. Fish is trying to say that its obvious that there are more than one way to say things he really just wants to teach whats been considered proper English not necessarily saying any one way to speak is incorrect. If he said "No i will teach you the right way to speak and write," than yes, this is not a correct statement. "If meant everybody should be thrilled to learn another dialect, then wouldn't everybody be learning everybody's dialect?" I think this is just a really bad assumption by Young into Fish's thinking when Fish says, "Who could object to learning a second language?" I believe Fish is just trying to avoid to offend anyone by saying that their English is not right so he's referring to the English he is teaching as a new one which is proper. Young is not trying to promote another dialect he is just questioning why someone wouldn't want to learn. "Grassley didn't send no standard English as a tweet ...If healthcare reform is so important to Obama, why is he sightseeing in Paris?" In this statement Young refers to Chuck Grassley's tweet referring to Obama and Young believes that he used specific terms in non-standard English just because people like code meshing. I believe he didn't use the sentence above because there is not as much anger in those words as there are in what he actually typed and not because of the code meshing, besides the all caps WKEND,  he used phrases like "you got nerve" and 'time to deliver' which are much stronger than the whole sentence Young thought he would've wrote if he used proper English.
