No, it does not matter. I'm an English teacher myself. I have enough difficulty teaching 9th graders that whatever way they choose to speak during their personal time is not always appropriate during school hours, and it probably won't be appropriate when they graduate and enter the work force. It's a delicate act to make sure you don't make them feel that the use of "finna", "ain't", etc. by themselves and their parents isn't wrong all the time (it's dialect/non-standard English), but it's a very important task that English teachers have to fulfill.
How in the world can I then teach them the correct way to use verbs and adverbs or even to be respectful of me, but I can let the "n" word slip out of my mouth??? "N___, you should say, 'May I?', not 'Can I'. You got that, lil N__?"
He needs to be smacked around.
OFF SUBJECT: Imagine how I feel each day having to teach a diverse poplulation to say "Chink Store" or "wetback" in class. They just don't get it. This generation unnerves me.
